Multiply: $\frac{-36}{5}\text{ by }\frac{20}{-3}$
✓
Answer
$\frac{-36}{5}\text{ by }\frac{20}{-3}$
$=\frac{20}{-3}=\frac{20\times(-1)}{-3\times(-1)}$
$=\frac{-20}{3}=\frac{20\times(-1)}{-3\times(-1)}$
$=\frac{-20}{3}$
$\therefore\frac{-36}{5}\times\frac{-20}{3}$
$=\frac{-36}{5}\times\frac{-20}{3}$
$=\frac{(-36)\times(-20)}{5\times3}$
$=\frac{(-12)\times(-4)}{1\times1}=\frac{48}{1}=48$
$=\frac{20}{-3}=\frac{20\times(-1)}{-3\times(-1)}$
$=\frac{-20}{3}=\frac{20\times(-1)}{-3\times(-1)}$
$=\frac{-20}{3}$
$\therefore\frac{-36}{5}\times\frac{-20}{3}$
$=\frac{-36}{5}\times\frac{-20}{3}$
$=\frac{(-36)\times(-20)}{5\times3}$
$=\frac{(-12)\times(-4)}{1\times1}=\frac{48}{1}=48$
