Best ResponseYou've already chosen the best response.0Can you help me w/ this? Add the following fractions. Be sure to find the common denominator (multiple) and then simplify

Best ResponseYou've already chosen the best response.0Did you find a common denominator for them?

Best ResponseYou've already chosen the best response.0In the first equation (3/16) the only thing to do is to carry out numerical division. So you will end up with 0.1875

Best ResponseYou've already chosen the best response.0No he's got to add two fractions by finding a common denominator, then adding the numerators of the equivalent fractions. Not convert to decimal...

Best ResponseYou've already chosen the best response.0Ok sorry. Just got what you really want. Wait. I definitively know what you want.

Best ResponseYou've already chosen the best response.0Those are the fractions (except it's 3/16). which part of the fraction is the denominator?

anonymous

Best ResponseYou've already chosen the best response.0Ok now Im gonna teach you how to get the common denominator.

Best ResponseYou've already chosen the best response.0\[\frac{Numerator}{Denominator}\]

Best ResponseYou've already chosen the best response.0The part on bottom is the denominator.

anonymous

Best ResponseYou've already chosen the best response.0So now, what are the two denominators you are working with?

anonymous

Best ResponseYou've already chosen the best response.0Correct. Now, we are looking for common multiplies of those two numbers. So what are the multiples of 16?

Best ResponseYou've already chosen the best response.0Do you see any multiples of 48 in that list?

Best ResponseYou've already chosen the best response.0What is the smallest multiple of 48 you see there?

anonymous

Best ResponseYou've already chosen the best response.0Ok the first thing you have to do is to divide the two numbers (16 and 48) in the denominator by 2. If they both are divisible by 2, then you save this number 2. Next, you have to devide the remaining of the last divison by two again. the new two numbers are 8 and 26. If both numbers are divisible by 2 again. You save this number (2) again. 16 48 * . 8 26 * 2 This number is saved 4 13 * 2 This number is saved too * Of course the remaining numbers are not divisible by 2 nor 3, and so on. This means the the common denominator is 2*2 =4 Question? Remember this is the first step

Best ResponseYou've already chosen the best response.048 is the smallest multiple that 16 and 48 have in common.

anonymous

Best ResponseYou've already chosen the best response.0So what do I do w/ the 48?

anonymous

Best ResponseYou've already chosen the best response.0So 16 * 3 = 48. Now we need to make both of the fractions have that denominator. Since 5/48 already has that for the denominator we don't need to change it.

anonymous

Best ResponseYou've already chosen the best response.0So you can just write 5/48 on the next column over. But to make 3/16 have a denominator of 48, we need to multiply the bottom by 3. In order to do that and keep the ratio the same, we must also multiply the top by 3.

Best ResponseYou've already chosen the best response.0\[\frac{3}{48} * \frac{3}{3} = ?\]

anonymous

Best ResponseYou've already chosen the best response.0Err. \[\frac{3}{16} * \frac{3}{3}\]

anonymous

Best ResponseYou've already chosen the best response.0We need to change the denominator of the 3/16 so it is also using our lowest common denominator.

anonymous

Best ResponseYou've already chosen the best response.0We can multiply any number by 1 without changing it. Since 3/3 = 1, we can multiply our fraction by 3/3 and it will still have the same value.

anonymous

Best ResponseYou've already chosen the best response.0But now it will have 48 for a denominator.
