Question

Efetue a operaçao 2/3:1/5-3/5

Answer 1

se eu entendi, temos:

$\frac{ \frac{2}{3} }{\frac{1}{5} } - \frac{3}{5}$
então:

$\frac{2}{3} \times \frac{5}{1} - \frac{3}{5} \\ \frac{10}{3} - \frac{3}{5} \\ \frac{(5 \times 10) -( 3 \times 3) }{(3 \times 5)} \\ \frac{50 - 9}{15} \\ \frac{41}{15}$
