I)3-1/4= J)2+1/5-6/7=
POR FAVOR ME AJUDEE!!​

Answer 1

Resposta:

A)6/9 + 3/9 = 9/9 ---> 1

B) 12/30 + 5/30 = 17/30

C)10/12 - 10/12 = 0

D) 3/6 + 2/6 = 5/6

E) 6/30 + 6/30 - 6/30 = 12/30 - 6/30 = 6/30 --> 1/5

F) 8/36 - 1/36 + 9/36 = 7/36 + 9/36 = 16/36 ---> 4/9

G)20/80 - 20/80 + 16/80 = 16/80 ---> 1/5

H) 2 1/4

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

J)2 1/5 - 6/7 = 2 7/35 - 30/35 = 1 42/35 - 30/35 = 1 12/35
