a)7/13 + 2/13
b)9/11 + 10/11
c)13/10 + 29/10
d)5/4 + 2/4
e)8/15 - 2/15
f)31/6 - 17/6
g)10/3 - 7/3
h)11/6 + 1/6 + 5/6​

Answer 1

Resposta:

a) 7 + 2 = 9

13 13 = 13

b) 9 + 10 = 19

11 + 11= 11

C) 13 + 29= 42

10 + 10 = 10

D) 5 + 2 = 7

4 + 4 = 4

E) 8 - 2 = 6

15 - 15 = 15

F) 31 - 7 = 31

6 - 6 = 6

G )10 - 7= 3

3 - 3 = 3

H)11 +1 + 5 17

6 + 6 + 6 = 6
