**Fractions**

## Addition and Subtraction of Fractions for Class 5 Maths

In this learning concept, students will learn about the addition and subtraction of fractions. Also, addition and subtraction of like fractions word problems. Students also can use their previous knowledge of fractions in class 4.

In this learning concept, the students will learn to

- Classify the addition of like fractions and the addition of unlike fractions.
- Evaluate subtracting of like fractions and subtracting of unlike fractions.
- Identify the fraction rules for addition and subtraction.

Each concept is explained to class 5 maths students using illustrations, examples, and mind maps. Students can assess their learning by solving the two printable worksheets given at the page’s end.

Download the addition and subtraction of fractions worksheets for class 5 and check the solutions for the addition and subtraction of fractions provided in PDF format.

**Addition of Like Fraction:**

Let us understand the addition of fractions having the same denominator by the following example.

**Example:**

Suppose we need to add Fraction that represents blue coloured part of the circle is

Fraction that represents total coloured part of the circle is

so,

**To add the fractions with the same denominator, add the numerators and keep the denominator as it is.**

**Addition of Unlike Fractions:**

Let us understand the addition of fractions having different denominators by the following example.

**Example:**

Suppose we need to add Fraction that represents the blue coloured part of the circle is

Fraction that represents total coloured part of both the circles is

**Since denominators (size of each part) are different, we cannot add numerators directly.**

So, we need to make denominators equal.

LCM of 6 and 8 = 24

Divide both the circles in 24 equal parts.

Fraction that represents the blue coloured part of the circle is

Fraction that represents the total-coloured part of both the circles is

**To add or subtract fractions, we need to make the denominators equal by using LCM of the denominators, and then add or subtract the numerators. **

**Subtraction of Like Fraction:**

Let us understand the subtraction of fractions having the same denominator by the following example.

**Example:**

Suppose we need to subtract Fraction that represents the blue coloured part of the circle is

There is one blue coloured part more than the red coloured parts.

**To subtract the fractions with the same denominator, subtract the numerators and keep the denominator as it is.**

**Subtraction of Unlike Fraction:**

Let us understand the subtraction of fractions having different denominators by the following example.

**Example:**

Suppose we need to subtract **Since denominators (size of each part) are different, we cannot subtract numerators directly.**

So, we need to make denominators equal.

LCM of 6 and 8 = 24

Divide both the circles in 24 equal parts.

Fraction that represents the blue coloured part of the circle is

Now,

There are six more blue parts than red coloured parts.

**To add or subtract fractions, we need to make the denominators equal by using LCM of the denominators, and then add or subtract the numerators. **

**Fraction Rules for Addition and Subtraction:**

**Step 1:**Check whether denominators are the same or not. If not, make the denominators the same by finding the LCM of denominators.**Step 2:**After making denominators the same, do the addition/subtraction of numerators.**Step 3:**Retain the same denominator.

**Misconception:**

A common misconception in the addition/subtraction of fractions is adding/subtracting different denominators.

When adding or subtracting fractions, very first important rule is to make common denominators.
