Question 4(a) :

Find the equivalent fraction of $\frac{3}{5}$ having:

denominator 20

Answer 1

Equivalent fractions are fractions which represent the same part of the whole.
To find an equivalent fraction of a given fraction, we may multiply or divide both the numerator and the denominator of the given fraction by the same number.

Now, $5\times 4=20$.

This means we need to multiply both the denominator and the numerator by 4.

The required equivalent fraction $=\frac{3}{5}=\frac{3\times 4}{5\times 4}=\frac{12}{20}$
