Question

calcule o valor da epressao (1/2 - 1/3)- (1/6-1/10

Answer 1

Resposta:(1/2-1/3)-(1/6-1/10)=

1/2 - 1/3 - 1/6 +1/10 = ---mmc(2,3,6,10) = 30

15/30 - 10/30 - 5/30 + 3/30 = 3/30 = 1/10

Explicação passo-a-passo: resolver o primeiro os parenteses

1/2-1/3 mmc (2,3)=6

3/6-2/6=1/6

1/6-1/10 mmc (6,10)=30

5/30-3/30=2/30

1/6-2/30 mmc (6,30)= 30

5/30-2/30=3/30 simplificando por 3 = 1/10

Resposta =

1/10
