Question

Calcule
7/12 ÷ 14/5 ?
-5 ÷ 15/4

Answer 1

Resposta:

7/12 ÷ 14/5= $\frac{35}{168}$           -5 ÷ 15/4 = $\frac{4}{3}$

Explicação passo-a-passo:

7/12 ÷ 14/5 => $\frac{7}{12} : \frac{14}{5} => \frac{7}{12} . \frac{5}{14} = \frac{35}{168}$

-5 ÷ 15/4 => $-\frac{5}{1} : \frac{15}{4} => -\frac{5}{1} . \frac{4}{15}=> -\frac{20}{15} => -\frac{20 : 5}{15 :5} => -\frac{4}{3}$
