Question

Multiply:
$\frac{25}{-9}\text{ by }\frac{3}{-10}$

✓

Answer

$\frac{25}{-9}\text{ by }\frac{3}{-10}$
$=\frac{25}{-9}\times\frac{3}{-10}=\frac{25}{-9}$
$=\frac{25\times(-1)}{-9\times(-1)}=\frac{-25}{9}$
$\frac{3}{-10}=\frac{3\times(-1)}{-10\times(-1)}$
$=\frac{-3}{10}=\frac{3\times(-1)}{-10\times(-1)}$
$=\frac{-3}{10}=\frac{(-25)\times(-3)}{9\times10}$
$=\frac{(-5)\times(-1)}{3\times2}=\frac{5}{6}$
