Question

1/4 - 3/4 - 3/2 - 1/2 /=fração

Answer 1

1/4 - 3/4 - 3/2 - 1/2

mmc = 4

1/4 - 3/4 - 6/4 - 2/4 = -10/4

Answer 2

Resposta: $\frac{-5}{2}$

Explicação passo-a-passo:

$\frac{1}{4} - \frac{3}{4} - \frac{3}{2} - \frac{1}{2}$=

$\frac{-2}{4} - \frac{4}{2}$=

MMC(4,2) = 4

$\frac{(-2-8)}{4}$ =

$\frac{-10}{4}$ =

$\frac{-10 : 2}{4 : 2}$ =

$\frac{-5}{2}$
