Answer 1

1.3 1/4-1 3/10
=3 5/20-1 6/20
=2 25/20-1 6/20
=1 9/20

2. 5 1/2- 3 1/4
= 5 2/4- 3 1/4
=2 1/4

Answer 2

1. 3 1/4 - 1 3/10 = ( 3-1 ) + ( 1/4 - 3/10 ) = 2 + ( 5/20-6/20 ) = 2 - 1/20 = 1 1/19
2. 5 1/2 - 3 1/4 = ( 5-3 ) + ( 1/2 - 1/4 ) = 2 + (2/4-1/4 ) = 2 1/4
3. 8 7/8 - 4 5/6 = ( 8-4) + ( 7/8 - 5/6 ) = 4 + ( 42/48-40/48) = 4 2/48 = 4 1/24
