Question

calcule
a)3/7 x 5/12
b) (-3/5) : 7/14​

Answer 1

Resposta:

a) 5/28

b) -6/5

Contas:

a)

$\frac{3}{7}$ × $\frac{5}{12}$

$\frac{3*5}{7*12}$

$\frac{15}{84}$

(Agora simplificar por 3)

$\frac{15:3}{84:3}$

$\frac{5}{28}$

b)

$(\frac{-3}{5})$ ÷ $\frac{7}{14}$

$-\frac{3}{5}$ × $\frac{14}{7}$

$-\frac{3}{5}$ × 2

$-\frac{6}{5}$
