The equivalent fractions are a type of fraction which seems to be different (not having the exact numbers) but they are equivalent in nature(having exactly equal value). Equivalent refers to being equal in value, function, amount or meaning and such things.

For example, an example of equivalent fraction is-

\(\frac{3}{9} = \frac{13}{39} = \frac{1}{3}\)

The biggest question here can be, why do they have equal values in spite of having different number?

The answer to this question is that, as the numerator and denominator are not co-prime numbers, therefore they have a common multiple which on division given an exactly the same value.

Take for an example:

\(\frac{1}{2} = \frac{2}{4} = \frac{4}{8}\)

But, it is clearly seen that the above fractions have different numbers as numerators and denominators.

Dividing both numerator and denominator by their common factor, we have:

\(\large \frac{4 \div 4}{8 \div 4}\)

= \(\large \frac{1}{2}\)

In the same way, if we simplify 2/4, again get 1/2.

\(\large \frac{2\div 2}{4\div 2}\)

= \(\large \frac{1}{2}\)

##### EQUIVALENT FRACTIONS

These fractions are actually the same because when we multiply or divide both, the numerator and the denominator by the same number, the value of the fraction actually doesn’t change. Therefore, equivalent fractions when reduced to their simplified value will all be the same.

For example, consider the fraction 1/5

Multiplying numerator and denominator with 2, we get 1/5 = 2/10

Multiplying numerator and denominator with 3, we get 1/5 = 3/15

Multiplying numerator and denominator with 4, we get 1/5 = 4/20

Therefore, we can conclude that,

\(\frac{1}{5} = \frac{2}{10} = \frac{3}{15} = \frac{4}{20}\)

Keep in mind that, we can only multiply or divide by the same numbers to get an equivalent fraction, and not add or subtract. Simplification to get equivalent numbers can be done till a point where both, the numerator and denominator should still be whole numbers.

Try the following question to check your understanding of the concept of equivalent fractions.

Example: The given fractions \(\frac{5}{6}\)

Solution:

Given- \(\frac{5}{6} = \frac{x}{12}\)

\(\Rightarrow x = \frac{5 \times12}{6}\)

\(\Rightarrow x = 10\)
