What is definition of equivalent fractions ? ??

 

A fraction obtained on multiplying or dividing both the numerator and denominator by the same non-zero number is called equivalent fraction. Such fractions express the same value of the part of a whole.
$$\begin{gathered} Example: \\ Consider the fraction \frac{15}{21} \\ Equivalent fraction of \frac{15}{21} can be calculated by multiplying and dividing a same number at the \\ numerator and denominator. \\ For example \\ \frac{15}{21} = \frac{15 ÷ 3}{21 ÷ 3} = \frac{5}{7} \\ \frac{15}{21} = \frac{15 \times 2}{21 \times 2} = \frac{30}{42} \\ Thus the equivalent fraction of \frac{15}{21} are \frac{5}{7}, \frac{30}{42} etc., \\ Regards \end{gathered}$$
