Question

(6/4)+(2/10)+(1/2)-(2/5)=

Answer 1

Olá, boa tarde ☺

Resolução:

(6/4) + ( 2/10) + (1/2) - (2/5)

m.m.c(2,4,5,10)= 20

30+4+10-8/20=36/20 ÷ 4 = 9/5

Resultado: 9/5.

Bons Estudos :)

Answer 2

Solução:

$\frac{6}{4} + \frac{2}{10} + \frac{1}{2} - \frac{2}{5}$
  

MMC (4, 10, 2, 5)

4, 10, 2, 5 / 2
2, 5, 1, 5 / 2
1, 5, 5 / 5
1, 1 / MMC → 20


$\frac{6}{4} + \frac{2}{10} + \frac{1}{2} - \frac{2}{5} = \frac{30+4+10-8}{20} = \frac{36}{20} = \frac{9}{5}$
