$\frac{-5}{3}\times\big(\frac{-3}{5}\big )=$ _____.
✓
Answer
$\frac{-5}{3}\times\big(\frac{-3}{5}\big )=1.$Solution:
GIven,
$\frac{-5}{3}\times\big(\frac{-3}{5}\big )$
$\therefore$ Product of rational numbers,
$=\frac{\text{Product of numerators}}{\text{Product of denominators}}$
$=\frac{(-5)\times(-3)}{3\times5}=\frac{15}{15}=1$
Hence,
$\frac{-5}{3}\times\big(\frac{-3}{5}\big)=1$
