Answer:
Equivalent fraction are the fractions whose simplest term is equal to simplest term of original fraction.
Equivalent fraction can be find using multiplication operation or division operation on numerator and denominator by same no.
⇒ Multiplication is used when we are given with a fraction and we need to find an equivalent fraction whose numerator and denominator is greater than given fraction.
For example,
Given fraction is

If we need to find equivalent fraction whose denominator is 64 then we use multiplication operation.
∵ Since Denominator of given fraction is 8 and denominator of equivalent fraction is 64. ⇒ we need to multiply 8 with 8 to get 64
So, if we multiply both numerator and denominator by 8 we get an equivalent fraction with denominator 64
