Question

Calcular essa conta de frações: - 1 - 3/2 : ( - 5/4) - 2 : ( - 3/4)

Answer 1

$-1- \frac{3}{2} : ( \frac{-5}{4} ) -2: ( \frac{-3}{4} )$

$-1 - \frac{3}{2} . \frac{-4}{5} -2 . \frac{-4}{3}$

-1 + $\frac{12}{10}$ + $\frac{8}{3}$

$\frac{-30 + 36 + 80}{30} = \frac{86}{30}: \frac{2}{2} = \frac{43}{15}$
