Question

reduce to lowest terms by canceling. a) 5/7x 6/5b) 5/-4 x (-8)/3c) -15/8 x (-2)/5d) 4 x (-12) x 5 / 10 x 3 x (-8)

Answer 1

$\begin{gathered} a) \\ \frac{5}{7}\times\frac{6}{5}=\frac{6}{7} \end{gathered}$$\begin{gathered} b) \\ \frac{5}{-4}\times\frac{-8}{3}=\frac{-8}{-4}\times\frac{5}{3}=2\times\frac{5}{3}=\frac{10}{3} \end{gathered}$$\begin{gathered} c) \\ -\frac{15}{8}\times\frac{(-2)}{5}=\frac{-15}{5}\times\frac{-2}{8}=-3\times\frac{-1}{4}=\frac{3}{4} \end{gathered}$$\begin{gathered} d) \\ 4\times(-12)\times\frac{5}{10}\times3\times(-8)=-48\times\frac{5}{10}\times-24=1152\times\frac{5}{10}=\frac{5710}{10}=576 \\ \end{gathered}$
