Question

A 33/56
B 1/5
C 5/8
D 23/40

Answer 1

A. 33/56

Explanation:

Make them have the same denominator of 56

so you get for the first one 49/56

the second one will be 16/56

subtract both and you get your answer of 33/56

Answer 2

Answer: A. 33/56

Explanation:

To get the number of pages left, all we need to do is to subtract 2/7 from 7/8

number of pages left = 7/8 - 2/7

=49 - 16 / 56

= 33/56
