b) 7/4

c)2/6

d)1/7

2) encontre 3 frações equivalentes.

b)2/3

c)6/8

Answer 1

Vamos lá:

1) a) (4/8)=(1/2)=(0,5)

b) (7/4)=(3,5/2)=(1,75)

c) (2/6)=(1/3)=0,333...

d) (1/7)=0,142857142857....

2) a) (1/5)×(2/2)=2/10; (1/5)×(3/3)=3/15; (1/5)×(4/4)=4/20

b) (2/3)×(2/2)=4/6; (2/3)×(3/3)=6/9; (2/3)×(4/4)=8/12

c) (6/8)×(2/2)=12/16; (6/8)×(3/3)=18/24; (6/8)×(4/4)=24/32

Bons estudos!
