e7 1/9-4 1/3=

g5 3/5-2 1/8=

h4 3/7-1 3/4=

Answer 1

a. 3/4+3/3 = 9/12 + 12/12 = 21/12 = 1 9/12 = 1 3/4

b. 1/5+3/7 = 7/35 + 15/35 = 22/35

c. 6 2/3+ 5 5/8 = 6 16/24 + 5 15/24 = 11 31/24 = 12 7/24

d. 4 3/5+ 4 3/4= 4 12/20+ 4 15/20= 8 27/20 = 9 7/20

e. 7 1/9 - 4 1/3= 7 1/9 - 4 3/9= 6 10/9 - 4 3/9 =2 7/9

g. 5 3/5 - 2 1/8 = 5 24/40 - 2 5/40=3 19/40

h. 4 3/7 - 1 3/4 = 4 12/28 - 1 21/28 = 3 40/28 - 1 21/28= 2 19/28
