Me ajudem : (

Answer 1

a) 1/3+1/5 = 8/15
b)3/4+1/2 = 3+2/4 = 5/4
c)2/4+2/3 = 6+8/12 = 14/12 = 7/6
d) 2/4+3/10 = 4+3/10 = 7/10
e) 5/3+1/6 = 10+1/6 = 11/6
f) 1/4+2/3+1/2 = 3+8+6/12 = 17/12

Answer 2

Resposta:

A-1/3+1/5 = 8/15

B-3/4+1/2 = 3+2/4 = 5/4

C-2/4+2/3 = 6+8/12 = 14/12 = 7/6

D- 2/4+3/10 = 4+3/10 = 7/10

E- 5/3+1/6 = 10+1/6 = 11/6

F- 1/4+2/3+1/2 = 3+8+6/12 = 17/12
