Question

Express $\frac{-3}{8}$as a rational number with a denominator $32$

Answer 1

Given a rational number is $\frac{-3}{8}$

To obtain the denominator $32$we have to multiply $4$ with the denominator of a given rational number.

If we multiply $4$ with the denominator, then we have to multiply with the numerator by $4$ also so that the value remains constant

Thus,

$\frac{-3}{8}=\frac{-3\times 4}{8\times 4}=\frac{-12}{32}$

Hence, the required rational number is $\frac{-12}{32}$
