Answer 1

OI...

a) 3/5 × 4/7 = 12/35

b) 2/3 × 4/5 = 8/15

c) 8 x 3/10 = 24/10 ÷ 2 = 12/5

d) 4/5 × 2/3 × 1/2 = 8/30 ÷ 2 = 4/15

e) 4/5 ÷ 2/3 = 4/5 × 3/2 = 12/10 ÷ 2 = 6/5

f) 4/9 ÷ 6/5 = 4/9 × 5/6 = 20/54 ÷ 2 = 10/27

g) 6/7 ÷ 5 = 6/7 × 1/5 = 6/35

h) 5 ÷ 2/3 = 5/1 × 3/2 = 15/2

Espero ter ajudado.
