Question

Resolva as frações abaixo e, simplifique, se necessário:

a) 2/4 + 1/6 =
b) 7/10 - 7/6 =
c) 3/5 × (3/8) =
d) 5/6 ÷ 5/9 =
e) (-4/5)^2 =
f) (-3,2)^3 =​

Answer 1

Resposta:

a) 1/2 + 1/6 = 3/6 +1/6 = 4/6 = 2/3

b) 7/10 - 7/6 = 21/30 - 35/30 = 56/30 = 28/15

c) 3/5 x 3/8 = 9/40

d) 5/6 ÷ 5/9 = 5/6 x 9/5 = 45/30 = 3/2

e) (-4/5)² = 16/25

f) $(-3,2)^{3}$ = $(-32/10)^{3}$ = -32768/1000 = -4096/125
