Question

como resolver: 4/5(7/3-1)/2/9-3

Answer 1

$<var>\frac{\frac{4}{5}(\frac{7}{3}-\frac{3}{3})}{\frac{2}{9}-\frac{27}{9}}= \frac{\frac{4}{5}(\frac{4}{3})}{\frac{-25}{9}}= \frac{\frac{16}{15}}{\frac{-25}{9}}= \frac{16}{15}*(\frac{-9}{25})= \frac{-144}{375}= \frac{-48}{125}</var>$

 

Acho que é isso..
