Question

2/3 + 1/6 - 3/4 =

Me ajudem por favor ​

Answer 1

$\frac{2}{3} + \frac{1}{6} - \frac{3}{4} \\ mmc = (3.6.4) = 12 \\ \frac{2}{3} \times 4 = \frac{8}{12} \\ \frac{1}{6} \times 2 = \frac{2}{12} \\ \frac{3}{4} \times 3 = \frac{9}{12} \\ \frac{8}{12} + \frac{2}{12} - \frac{9}{12} = \frac{10}{12} - \frac{9}{12} = \frac{1}{12} .$

mmc em modo fatorial:

3,6,4|2

3,3,2|2

3,3,1|3

1,1,1 = 2x2x3=4x3=12

tá aí os cálculos

Answer 2

R: 1/12

Explicação passo-a-passo:

mmc de 3 6 4 = 12

8+2-9/12=
