b)3 3/4 - 1/2 =

c) 10 3/4 - 2 1/2 =

d) 5 1/4 + 3 1/2 =

Answer 1

a)1 1/2+1/4 = 3/2 + 1/4 = 6/4 + 1/4 = 7/4 = 1 3/4

b)3 3/4 - 1/2 = 3 3/4 - 2/4 = 3 1/4

c)10 3/4 - 2 1/2 = 10 3/4 - 2 2/4 = 8 1/4

d)5 1/4 + 3 1/2 = 5 1/4 + 3 2/4 = 8 3/4

Answer 2

1 1/2 + 1/4=1 2/4 + 1/4=1  3/4

3 3/4-1/2= 3 3/4-2/4=3 1/4

10 3/4 - 2 1/2=10 3/4 -2 2/4=8 1/4

5 1/4+3 1/2=5 1/4+3 2/4=8 3/4
