For example:
Finding the LCD of 2/3, 5/12, and 7/15 we would list multiples of 3, 12 and 15

The other method involves factorizing your denominator

And is often a bit faster.

so what if i have big number like, 220 and say 100....?

Yeah, that's when factorizing helps.
What are the factors of 220?

how do you find the factors?

22 * 10 = 220
(11*2)*(5*2) = 220
So the factors of 220 are 2*2*5*11

oh, ok thanks!!

Does that make sense as to how you break them down?

yea sort of, i'm a little bit rusty when it comes to math....

So now, what are the factors of 100?

Pick two numbers you can multiply to get 100

hold up one second

ten and one??

ten times one is ten.

ok sorry, i ment ten times ten and 1 times 100

But \(10\times 10\) is good. So now, what two numbers do you multiply to get 10?

5x2 and 1x10 are the only ones i can think of right off the top of my head

Right, those are the only ones. But again, the 1x10 is not useful. So we'll use 5x2

So that means that
\(100 = 10\times 10\)
\(100 = (5\times 2)\times (5\times 2)\)

So the factors of 100 are?

10?

No. 2*2*5*5

sorry, like i said, a bit rusty

You take each number in your fully factored form those are your factors

In this case we had 2*5*2*5 = 100, so 2, 2, 5, 5 would be our factors.

oh, wow, thank you so much for your help!!!

and the lowest is two, so the LCD would be 2??

No, that's the LCF

ok so whats the LCD then?

The lowest common factor is 2, but the lowest common divisor is actually bigger than 100, or 220

And we see that if we want them to have the same factors, we need a 11 times 100 and a 5 times 220

What is 11 * 100?

im looking for the lowest common denominator, not the divisor..

100= 2*2 * 5*5
220= 2*2 * 5 * 11
Sorry I meant denominator

oh ok, i was getting a bit confused fro a second,

So again, both of our numbers have 2 2's, and one 5.

But one has an extra 5, and the other has an 11.

Do you see that?

yep i do!

Ok, so we have to make them the same

oh ok!

So what is 5 * 220, and 100 * 11?

1100

yep.
Now lets have you try it with either another problem you have, or my earlier example

ok lets see, how about, 95 and 100

yep and its 10x10

No, you can factor that further remember?

10 is 5*2, so 100 is 5*2 * 5*2

oh yea sorry, i am so sorry i apparently have lack of memory

anyways, do go on...

Ok, so factor 95

ok 5x19 is one i know

but i cant think of any others

That's good. There are no others.

oh ok

ok so, 100: 5x2 5x2 and for 95: 5x19
so the all have fives

Ok, which ones do they not have in common?

19 and 2

Ok, specifically if we wanted to make them the same, what would we need to multiply by 100

not really sure....

100 has all the ones 95 has except?

19

Good. And 95 has all the ones 100 has except?

Close. It's actually two 2's and a 5. You have to count how many each one has.

oh ok so with that how do you make them the same?

Well you multiply the 100 by the ones it's missing (19) and the 95 by the ones it's missing (2*2*5)

And they should be the same.

and it would equal to 1900

100 * 19 = 1900, what about 95*2*2*5?

it equals the same, 1900

Yep, that's your LCD

Ok try another one on your own.

i will! thanks for all your help!!

Any time =)

wow i just did one on my own and i got it right, thank you for helping me understand!

Very welcome! =)

but i might need help on something else, if you have the time

Of course, just start a new question and I'll take a look.

Ok, well start by turning the mixed number into a fraction.

for example, 5 3/8 percent into a fraction

Right, so start by turning the 5 3/8% into a improper fractional percentage

Basically ignore the percent for now.

ok hold up

dont you multiplie the 5 by 3 then add 8, or am i getting this mixed up

dont you do this: 5x3+8 then keep eight as your denominater

No, for improper fractions, you need to rewrite 5 as \(\frac{x}{8}\)

Then add it to the 3

sorry, i dont know what that is

ok, i kind of get it but kind of dont, if that makes any sense

like where did the one and the eight come from>

Well, you can always multiply 1 times something and get the same thing right?

right...

\[\frac{5}{1} = \frac{5}{1}*1\]

oh ok....

And any number over itself is 1 right?

right

ok now it makes sense.... so ow that we have the 40/8 what do we do with it?

So then we add it to the fractional part.

So 5 and 3/8 as a fraction is 40/8 + 3/8

43/8...?

Yep. So 43/8 %

But we want that as just a fraction, not a percent.

right...

So to turn a percent into fraction a we just multiply the denominator by 100.

yep and that would be 800?? because you multiply 8 x 100= 800

Yep.

So 5 and 3/8 % = 43/800

oh ok..

So now you try one.

ok, and i will let you know if i get it right

ok

No. 5 * 100 = 500, not 100.

thats what i ment sorry

Then yes, 44/500 is correct.

yay! thanks! and im sure i will have more questions, so when i do, ill just ask!

ok

how do i give you a medal?

ok, i have another question.....

nevermind!

Sorry, I had class. To give a medal you click the give medal button. next to any of my posts..
