Question

(2/7×1/4): (3/4-1/5)

Answer 1

Resposta:

$\frac{10}{77}$

Explicação passo a passo:

$\frac{\frac{2}{7}\times \frac{1}{4}}{\frac{3}{4}-\frac{1}{5}}$

$=\frac{\frac{2}{7}\times \frac{1}{4}}{\frac{11}{20}}$

$=\frac{\frac{1}{14}}{\frac{11}{20}}$

$=\frac{1\times \:20}{14\times \:11}$

$=\frac{20}{14\times \:11}$

$=\frac{20}{154}$

$=\frac{10}{77}$
