Answer 1

Hi GtaMods402,

Solution:

5/8 = 25/40

3/10 = 12/40

25/40 - 12/40 = 13/40

Answer:

A. 13/40

Answer 2

5/8 - 3/10

Find the common denominator:

Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)

Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)

5/8 = 5*5 / 8*5 = 25/40

3/10 = 3*4 / 10 *4 = 12/40

Now you have 25/40 - 12/40

25 -12 = 13

Answer = 13/40

The answer is A.
