Unlike fractions definition explained with examples

Learn and know what is unlike fractions definition? In mathematics, In the fractions concept. In fractions, other than proper fraction, improper fraction and mixed fraction, like fractions and unlike fractions are very important concepts.

Unlike fractions definition explained

First, we will know why we need to learn fractions? If there is a square sheet and if it is cut into four equal pieces then what does each piece represents? How to represent it in mathematical notation? This thing we learn in fractions. Now what is a fraction? We will learn. “The Part of whole or one entire thing is called as fraction”. In that we have so many types of fractions, among them unlike fractions is one. Now we will learn about this i.e. what are unlike fractions, unlike fractions definition and how to add unlike fractions.

Definition of unlike fractions as follows:                                                   

Unlike fractions definition will be exactly opposite to the like fractions definition. Anyhow, unlike fractions are defined as “the fractions whose denominators are not same or not equal are called as unlike fractions”. If you consider any two or more fractions and if all the denominators are different values then we call them as unlike fractions.


The fractions \frac { 8 }{ 9 } , \frac { 6 }{ 5 } , \frac { 3 }{ 11 } are called as unlike fractions. This is because all the fractions denominators are different values.

How to add unlike fractions?

We know that adding like fractions is so simple and within sec we do that. What about adding unlike fractions? Yes this is also so simple only. What we need to do is we need to convert unlike fractions to like fractions. That’s it then you know how to add them.

Do you know how do we convert the unlike fractions to the like fractions?

Let us consider an example. Let \frac { 8 }{ 9 } and \frac { 6 }{ 5 } be unlike fractions.

Step 1: find L.C.M of denominators 9 and 5. The L.C.M of 9, 5 is 45.

Step 2: make denominator as 45 in the two given fractions.

Step 3: in the first fraction, the denominator is 9. So multiply 9 by 5, we get 45. Numerator also we should multiply with 5, we get 40.

Step 4: in the second fraction, the denominator is 5. So multiply 5 with 9, we get 45. Numerator also we should multiply with 9, we get 54.

Step 5: now the two new fractions we got are \frac { 40 }{ 45 } and \frac { 54 }{ 45 } , clearly these two fractions are like fractions.

Step 6: now you know how to add like fractions. Add numerator and write denominator as it is. \frac { 40+54 }{ 45 } = \frac { 94 }{ 45 } .
