Answer 1

Resposta:

Explicação passo-a-passo:

a) 3/5 ÷ 3/2 = 3/5 x 2/3 = 3.2/5.3 = 2/5.

b) -4/9 ÷ 2/3 = -4/9 x 3/2 = -4.3/9.2 = -2/3.

c) -3/7 ÷ (-2/9) = -3/9 x (-9/2) = -3.9/(-9.2) = 3/2.

d) -1/3 ÷ (-1/5) = -1/3 x (-5/1) = 5/3.

e) 2/3 ÷ 4/5 = 2/3 x 5/4 = 2.5/3.4 = 5/6.

f) -1/2 ÷ 5/8 = -1/2 x 8/5 = - 1.8/2.5 = - 4/5.
