Similar (Like) fractions are fractions with same denominators. On the other hand, dissimilar (Unlike) fractions are fractions with different denominators.

SIMILAR FRACTION |
Fractions with same denominators (bottom numbers). ## Examples:`1/6` , `5/6` , `13/6` , `19/6` |

UNLIKE FRACTION |
Fractions with different denominators (bottom numbers). ## Examples:`2/9` , `7/8` , `14/25`, `26/4` |

Since `5/11` and `8/11` have similar denominators. Therefore, they are similar fractions.

Since `2/5` and `5/2` have unlike denominators. Therefore, they are unlike fractions.

Since `1/4` and `6/8` have unlike denominators, they are unlike fractions.

**Step 1**

Find LCM (least common multiple) of the denominators.

**Step 2:**

Convert the fractions to equivalent fractions with denominators equal to the LCM.

**Step 1**

The least common multiples of 4 are: 4, 8, 12, 16…

The least common multiples of 8 are: 8, 16, 24, 32…

**Step 2**

The least common multiple of 4 and 8 is 8, so our aim is to make both the denominators 8.

We achieve this by multiplying the denominator and numerator of the first fraction `1/4` by 2.

`1/4` = `(1 text( x ) 2)/(4 text( x ) 2)` = `2/8`

Similarly, we multiply the denominator and numerator of the second fraction `3/8` by 1.

`3/8` = `(3 text( x ) 1)/(8 text( x ) 1)` = `3/8`

The new fractions, `2/8` and `3/8` are now similar fractions.

We convert unlike fractions to similar fractions when we have to add or subtract two unlike fractions.
