Dear Student!

A fraction can be converted into an equivalent fraction by multiplying or dividing both the numerator and denominator by the same non-zero number.

Consider the fraction $\frac{15}{21}$ .

Equivalent fraction of $\frac{15}{21}$ can be obtained by multiplying or dividing a same number in the numerator and denominator.

$\frac{15}{21} = \frac{15 \div 3}{21 \div 3} = \frac{5}{7} \frac{15}{21} = \frac{15 \times 2}{21 \times 2} = \frac{30}{42}$

Thus, the equivalent fraction of $\frac{15}{21}$ are $\frac{5}{7}, \frac{30}{42}$ etc.

Cheers!
