Question

(-4/9+1/15):(-5/6-1/9)

Answer 1

($\frac{-4}{9}+ \frac{1}{15}$) : ($\frac{-5}{6}- \frac{1}{9}$) =

$\frac{5.(-4)+3.1}{45}$ : $\frac{3.(-5)-2.1}{18}$ =

$\frac{-20+3}{45}$ : $\frac{-15-2}{18}$ =

$\frac{-17}{45}$ : $\frac{-17}{18}$ =

$\frac{-17}{45}$ x $\frac{18}{-17}$ =

$\frac{18}{45}$ = $\frac{2}{5}$
