Question

The product of 8/15, 6/5, and 1/3 is

A. 48/15.
B. 16/15.
C. 16/75.
D. 48/30

Answer 1

Okay to make life easy lets start by multiplying the denominators (bottom), 15*5*3=225. Now we need to do is multiply all the numerators (top), 8*6*1=48. So now we have 48/225, but this isn't complete we now need to simplify this. Both the denominator and the numerator can be divided by 3, leaving us with 16/75.

Answer 2

You must multiply the all the numerators first. This is 8 x 6 x 1 = 48. Therefore you know 48 will be the top number. Now you multiply the denominators 15 x 5 x 3 =  225. Therefore the answer will be 48/225. However you can simply this fraction. Now you must think of a number that both 48 and 225 are divisible by, in this case it is 3. Therefore the answer is 16/75.
