Question

Perform the indicated operation.
13/16 - 3/8

I got 56/128 in all, but it needs to be lowered as low as it can get. How would I do this?

Answer 1

3/8 = 6/16

so the problem is

13/16 - 6/16
after using an equivalent fraction and common denominators

which can be written

\[\frac{13 - 6}{16}\]

just complete the subtraction in the numerator for the answer

Answer 2

as a fraction you need 13 - 6 = 7

so the answer is 7/16

Answer 3

How did you get the 6?

Answer 4

3/8 double the top and bottom of the fraction gives 6/16 this is called an equivalent fraction. That ,means it has the same value as 3/8 but can be written in a different way
