Answer 2

A)
3 4/5 - 2/5 = 3 2/5 
5 5/8 - 2 1/8 = 3 4/8 = 3 1/2

b)
2 - 3/8 = 1 8/8 - 3/8 = 1 5/8
3 - 1 5/6 = 2 6/6 - 1 5/6 = 1 1/6

c)
2 3/8 - 5/8 = 1 11/8 - 5/8 = 1 6/8 = 1 3/4
4 2/9 - 7/8 = 4 16/72 - 63/72 = 3 88/72 - 63/72 = 3 25/72 

d)
3 1/4 - 1 3/4 = 2 5/4 - 1 3/4 = 1 2/4 = 1 1/2
4 1/6 - 2 5/6 = 3 7/6 - 2 5/6 = 1 2/6 = 1 1/3
