Answer 1

a-13/6 b-3/7 c-11/12 d-3/5 e-3/5 f-3/5 g-31/36 h-9/6 i-3/5 j-1/6 l-10/9 m- 3/7
acho q ta certo

Answer 2

a) 3/2 + 2/3 = 9/6 + 4/6 = 13/6

b) 2/7 +1/7 = 3/7

c) 2/3 - 1/4 = 8/12 - 3/12 = 5/11

d) 4/5 - 1/5 = 3/5

e) 7/5 - 4/5 =3/5

f) 1/5 + 2/5 = 3/5

g) 7/12 + 5/18 = 21/36 + 10/36 = 31/36
