Question

Multiply:

viii) $35\text{and}\frac{-18}{25}$

Answer 1

Step : Multiplying the given rational
numbers
Given numbers, $35$ and $\frac{-18}{25}$
$\because$ Product of two rational numbers
$=\frac{\text{Product of the numerators}}{\text{Product of the denominators}}$
$\therefore 35\times \frac{-18}{25}=\frac{35}{1}\times \frac{-18}{25}$
$=\frac{35\times (-18)}{1\times 25}$
$=\frac{-7\times 5\times 18}{5\times 5}$
$=-\frac{126}{5}=-25\frac{1}{5}$

Hence, the required product is $-25\frac{1}{5}$.
