Question

62 Efetue as divisões. a) 1/6 ÷ 3/5 = b) 3/4 ÷ 2/9 =c) 3 ÷ 1/45 = d) 20÷ 4/5 =​ e) 2 1/3 ÷ 4 2/6

Answer 1

Vamos lá.

a)

(1/6)/(3/5)

multiplique a primeira pelo inverso da segunda

(1/6)*(5/3) = 5/18

b)

(3/4)/(2/9) = (3/4)*(9/2) = 27/8

c)

(3/1)/(1/45) = (3/1)*(45/1) = 135

d)

20/(4/5) = 100/4 = 25

e)

2 1/3 = 7/3

4 2/6 = 26/6 = 13/3

(7/3)/(13/3) = 7/13
