Question

Como resolver essa divisão de fração

Answer 1

Explicação passo-a-passo:

letra A:

6/2÷ 7/1 = 6/2 .(1/7)= 6.1/7.2=6/14

= 6÷2/14÷2= 1/7

letra B:

6/5÷2/1= 6/5.(1/2)= 6.2/2.5=6/5

letra c:

2/3÷ 4/5 / 5/3 ÷2/3

= 2/3.(5/4) ÷ (5/3).(3/2)

= 10/12 ÷ 15/6

= 10/12.(6/15)

= 60/180

= 6/18

= 1/3

letra D:

4/15÷2/3 / 12/24÷3/8

4/15.(3/2)/ 12/24.(8/3)

= 12/30÷ 96/72

= 6/15÷32/24

= 2/5÷16/12

= 2/5÷8/6

= 2/5÷4/3

= 2/5.(3/4)

= 6/20
