Equivalent Fractions

Equivalent fractions are different fractions that represent the same part of a whole having the same value. This equivalence results from multiplying or dividing the numerator and the denominator by the same number.

Examples

What Fraction is Equivalent to 1-2
What Fraction is Equivalent to 1-3

Here are some more equivalent fractions.

How To Represent

We can represent equivalent fractions by comparing them on a bar model or number lines.

Let us represent ${\dfrac{1}{5}}$ and its equivalent fraction ${\dfrac{2}{10}}$

Using Bar Model

Equivalent Fractions with Models

${\dfrac{1}{5}}$ is equivalent to ${\dfrac{2}{10}}$

Using Number Line

Equivalent Fractions on Number Lines

${\dfrac{1}{5}}$ is equivalent to ${\dfrac{2}{10}}$

How To Find

To get equivalent fractions, we multiply or divide the numerator and denominator of a given fraction by the same number.

Multiplying by the Same Number

Let us find the equivalent fractions of ${\dfrac{3}{4}}$ by multiplying both numerator and denominator by the same number.

What Fraction is Equivalent to 3-4

Here, ${\dfrac{6}{8}}$ and ${\dfrac{12}{16}}$ are equivalent fractions of ${\dfrac{3}{4}}$.

Dividing by the Same Number

Let us find the equivalent fractions of ${\dfrac{30}{20}}$ by dividing both numerator and denominator by the same number.

What Fraction is Equivalent to 3-2

Here, ${\dfrac{15}{10}}$ and ${\dfrac{3}{2}}$ are equivalent fractions of ${\dfrac{30}{20}}$.

For Mixed Numbers

If the given mixed fraction is ${1\dfrac{2}{3}}$

First, we will convert the mixed number into an improper fraction and then find its equivalent fractions.

${1\dfrac{2}{3}}$ = ${\dfrac{\left( 1\times 3\right) +2}{3}}$ = ${\dfrac{5}{3}}$

Thus, the equivalent fractions of ${\dfrac{5}{3}}$ are:

${\dfrac{5\times 2}{3\times 2}}$ = ${\dfrac{10}{6}}$

${\dfrac{5\times 3}{3\times 3}}$ = ${\dfrac{15}{9}}$

${\dfrac{5\times 4}{3\times 4}}$ = ${\dfrac{20}{12}}$

${\dfrac{5\times 5}{3\times 5}}$ = ${\dfrac{25}{15}}$

How To Determine

Making the Denominators the Same

Let us determine whether ${\dfrac{5}{10}}$ and ${\dfrac{1}{2}}$ are equivalent.

Since ${\dfrac{1}{2}}$ = ${\dfrac{5}{10}}$, the given fractions are equivalent.

How to Determine Equivalent Fractions

Cross Multiplying

Now, by cross-multiplying the fractions ${\dfrac{5}{10}}$ and ${\dfrac{1}{2}}$ fractions, we get

Cross Multiply to Find Equivalent Fractions

Since both the products are equal, the fractions ${\dfrac{5}{10}}$ and ${\dfrac{1}{2}}$ are equivalent fractions.

Converting to Decimals

Finding their decimal numbers is also a way to verify whether the given fractions are equivalent.

Converting ${\dfrac{5}{10}}$ and ${\dfrac{1}{2}}$ to the decimal form, we get

Solved Examples

Verify whether the fractions ${\dfrac{12}{18}}$ and ${\dfrac{16}{24}}$ are equivalent.

Solution:

In the given fractions, the denominators are 18 and 24
LCM of 18 and 24 are 72
Now, for making the denominators of the given fractions equal, we get
${\dfrac{12\times 4}{18\times 4}}$ = ${\dfrac{48}{72}}$
${\dfrac{16\times 3}{24\times 3}}$ = ${\dfrac{48}{72}}$
Thus the fractions ${\dfrac{12}{18}}$ and ${\dfrac{16}{24}}$ are equivalent.

Is ${\dfrac{8}{12}}$ an equivalent fraction of ${\dfrac{2}{3}}$

Solution:

Here, 
On dividing the numerator and the denominator of ${\dfrac{8}{12}}$ by 4, we get
${\dfrac{8\div 4}{12\div 4}}$ = ${\dfrac{2}{3}}$
Thus, ${\dfrac{8}{12}}$ is an equivalent fraction of ${\dfrac{2}{3}}$
