Answer 1

7 3/4 - 2 2/5
(7-2)+(3/4-2/5)
5+7/20

5 and 7/20 or 5.35

Answer 2

5 7/20

Explanation:

basically, you are going to want to turn these into improper fractions

7 3/4 = 28/4 + 3/4

= 31/4 (no further simplification)

2 2/5 = 10/5 + 2/5

= 12/5

now get common denominator to subtract

31/4 - 12/5

155/20 - 48/20 = 107/20

if you want this back into mixed fraction then convert

107/20 = 5 7/20
