Best ResponseYou've already chosen the best response.0Find multiples of each the denominators and see which ones they all have in common. Then choose the smallest of those to be your LCD.

anonymous

Best ResponseYou've already chosen the best response.0For example: Finding the LCD of 2/3, 5/12, and 7/15 we would list multiples of 3, 12 and 15

anonymous

Best ResponseYou've already chosen the best response.0The other method involves factorizing your denominator

anonymous

Best ResponseYou've already chosen the best response.0And is often a bit faster.

Best ResponseYou've already chosen the best response.0so what if i have big number like, 220 and say 100....?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Yeah, that's when factorizing helps. What are the factors of 220?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0how do you find the factors?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.022 * 10 = 220 (11*2)*(5*2) = 220 So the factors of 220 are 2*2*5*11

anonymous

Best ResponseYou've already chosen the best response.0Does that make sense as to how you break them down?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yea sort of, i'm a little bit rusty when it comes to math....

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So now, what are the factors of 100?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Pick two numbers you can multiply to get 100

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ten times one is ten.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok sorry, i ment ten times ten and 1 times 100

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yeah, don't bother with 1, it's not useful when factoring, because you can factor infinitely many ones from any number

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0But \(10\times 10\) is good. So now, what two numbers do you multiply to get 10?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.05x2 and 1x10 are the only ones i can think of right off the top of my head

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Right, those are the only ones. But again, the 1x10 is not useful. So we'll use 5x2

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So that means that \(100 = 10\times 10\) \(100 = (5\times 2)\times (5\times 2)\)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So the factors of 100 are?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0sorry, like i said, a bit rusty

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0You take each number in your fully factored form those are your factors

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0In this case we had 2*5*2*5 = 100, so 2, 2, 5, 5 would be our factors.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh, wow, thank you so much for your help!!!

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, so now we take the factors of 100 and the factors of 220 and compare them: 100= 2*2 * 5*5 220= 2*2 * 5 * 11

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0and the lowest is two, so the LCD would be 2??

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok so whats the LCD then?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0The lowest common factor is 2, but the lowest common divisor is actually bigger than 100, or 220

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0And we see that if we want them to have the same factors, we need a 11 times 100 and a 5 times 220

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0im looking for the lowest common denominator, not the divisor..

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0100= 2*2 * 5*5 220= 2*2 * 5 * 11 Sorry I meant denominator

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh ok, i was getting a bit confused fro a second,

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So again, both of our numbers have 2 2's, and one 5.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0But one has an extra 5, and the other has an 11.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, so we have to make them the same

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So we need to multiply 100 times 11, and 220 by 5 and they will have the same factors and therefore be the same number. And that number is our LCD.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So what is 5 * 220, and 100 * 11?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yep. Now lets have you try it with either another problem you have, or my earlier example

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok lets see, how about, 95 and 100

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, so first factor them like we did before, 100 is easy since we already had that one the last time.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No, you can factor that further remember?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.010 is 5*2, so 100 is 5*2 * 5*2

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh yea sorry, i am so sorry i apparently have lack of memory

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok 5x19 is one i know

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0but i cant think of any others

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0That's good. There are no others.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So list the factors of 100, and the factors of 95 side by side and see which ones they have in common and which ones they do not.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok so, 100: 5x2 5x2 and for 95: 5x19 so the all have fives

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, which ones do they not have in common?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, specifically if we wanted to make them the same, what would we need to multiply by 100

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0100 has all the ones 95 has except?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Good. And 95 has all the ones 100 has except?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Close. It's actually two 2's and a 5. You have to count how many each one has.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0oh ok so with that how do you make them the same?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Well you multiply the 100 by the ones it's missing (19) and the 95 by the ones it's missing (2*2*5)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0And they should be the same.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0and it would equal to 1900

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0100 * 19 = 1900, what about 95*2*2*5?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0it equals the same, 1900

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok try another one on your own.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i will! thanks for all your help!!

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0wow i just did one on my own and i got it right, thank you for helping me understand!

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0but i might need help on something else, if you have the time

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Oh, when you can, go ahead and give me a medal, that's how the site determines whether or not the question is answered.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Of course, just start a new question and I'll take a look.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, i have these problems where im supposed to change a percent that is a mixed number into a fraction (in lowest terms) and the book gives me no help on how to do it

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, well start by turning the mixed number into a fraction.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0for example, 5 3/8 percent into a fraction

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Right, so start by turning the 5 3/8% into a improper fractional percentage

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Basically ignore the percent for now.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0dont you multiplie the 5 by 3 then add 8, or am i getting this mixed up

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0dont you do this: 5x3+8 then keep eight as your denominater

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No, for improper fractions, you need to rewrite 5 as \(\frac{x}{8}\)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0sorry, i dont know what that is

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.05 and 3/8 \[= 5 + \frac{3}{8}\]\[ = \frac{5}{1} + \frac{3}{8}\] \[= \frac{5}{1} * 1 + \frac{3}{8}\] \[= \frac{5}{1}*\frac{8}{8} + \frac{3}{8}\] \[= \frac{40}{8} + \frac{3}{8}\] \[= \frac{43}{8}\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, i kind of get it but kind of dont, if that makes any sense

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0like where did the one and the eight come from>

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Well, you can always multiply 1 times something and get the same thing right?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0\[\frac{5}{1} = \frac{5}{1}*1\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0And any number over itself is 1 right?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0\[\frac{8}{8} = 1 \implies \frac{5}{1}= \frac{5}{1}*1 = \frac{5}{1}*\frac{8}{8} = \frac{40}{8}\] This is just a very long way to say that \[5 = \frac{40}{8}\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok now it makes sense.... so ow that we have the 40/8 what do we do with it?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0You could also answer that by just taking the denominator and multiplying it by the whole number part.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So then we add it to the fractional part.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So 5 and 3/8 as a fraction is 40/8 + 3/8

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Take the denominator. Multiply it by the whole number. Then add that to the numerator of the fractional part. That's your improper fraction.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0But we want that as just a fraction, not a percent.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So to turn a percent into fraction a we just multiply the denominator by 100.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yep and that would be 800?? because you multiply 8 x 100= 800

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So 5 and 3/8 % = 43/800

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, and i will let you know if i get it right

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, heres my problem: 8 4/5 change it into a percent: i got 44/5 then multiplied it by 100 and got 44/100... is that correct?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No. 5 * 100 = 500, not 100.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0thats what i ment sorry

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Then yes, 44/500 is correct.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yay! thanks! and im sure i will have more questions, so when i do, ill just ask!

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0how do i give you a medal?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, i have another question.....

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Sorry, I had class. To give a medal you click the give medal button. next to any of my posts..
