8/5 ÷ 1/3 ÷ 2/4=

1/7÷3/2÷2/5÷4/6

2/3÷4/5÷1/5÷2/7=

3/5÷1/5÷2/3÷6=

5/9÷2/3÷3÷1/4= 7/3÷4/5÷1/3÷2=

Answer 1

Explicação passo a passo:

a

8/5 ÷ 1/3 ÷ 2/4=8/5 * 3/1 * 4/2 = 96/10 = por 2 = 48/5 >>>>>> resposta

b

1/7÷3/2÷2/5÷4/6= 1/7 * 2/3 * 5/2 * 6/4 = 60/168 por 12 = 5/14 >>>>>resposta

2/3÷4/5÷1/5÷2/7= 2/3 * 5/4 * 5/1 * 7/2 =350/24 =por 2 = 175/12>>>>resposta

c

3/5÷1/5÷2/3÷6= 3/5 * 5/1 * 3/2 * 1/6 = 45/60 =por 15 = 3/4>>>>>resposta

d

5/9÷2/3÷3÷1/4= 5/9 * 3/2 * 1/3 * 4/1 = 60/54 = por 6 = 10/9 >>>>>resposta

e

7/3÷4/5÷1/3÷2= 7/3 * 5/4 * 3/1 * 1/2 =105/24 =por 3 = 35/8>>>>>resposta
