### How to Add Fractions using a Fraction Number Line?

Follow the step-by-step procedure to Add Fractions using a Fraction Number Line.

- Take the number line and divided it into equal parts.
- Divide the line into n equal parts where n is the denominator of the fraction.
- Take the first part of the fraction on a number line and add the second fraction to the first fraction.
- Then, take the last fraction as the final output of the addition of the fraction.

### Examples on Addition of Fractions using a Number Line

Check out the below examples to add different fractions with the help of a number line.

**Example 1.**

Calculate the sum of \(\frac { 6 }{ 10 } \) + \(\frac { 3 }{ 10 } \) on the fraction number line.

**Solution: **

Given fractions are \(\frac { 6 }{ 10 } \) + \(\frac { 3 }{ 10 } \)

The denominator is 10.

Take the number line and divide it into 10 equal parts.

First, take 6 parts out of 10 parts because the first fraction is \(\frac { 6 }{ 10 } \) on a number line.

Add 3 parts from the 6 out of 10 parts because the second fraction is \(\frac { 3 }{ 10 } \) on a number line.

\(\frac { 6 }{ 10 } +\frac { 3 }{ 10 } =\frac { 9 }{ 10 } \)

Finally, the final output is \(\frac { 9 }{ 10 } \).

**Example 2.**

Calculate the sum of \(\frac { 2 }{ 5 } \) + \(\frac { 2 }{ 5 } \) on the fraction number line.

**Solution: **

Given fractions are \(\frac { 2 }{ 5 } \) + \(\frac { 2 }{ 5 } \)

The denominator is 5.

Take the number line and divide it into 5 equal parts.

First, take 2 parts out of 5 parts because the first fraction is \(\frac { 2 }{ 5 } \) on a number line.

Add 2 parts from the 2 out of 5 parts because the second fraction is \(\frac { 2 }{ 5 } \) on a number line.

\(\frac { 2 }{ 5 } +\frac { 2 }{ 5 } =\frac { 4 }{ 5 } \)

Finally, the final output is \(\frac { 4 }{ 5 } \).

**Example 3.**

Calculate the sum of \(\frac { 1 }{ 7 } \) + \(\frac { 4 }{ 7 } \) on the fraction number line.

**Solution: **

Given fractions are \(\frac { 1 }{ 7 } \) + \(\frac { 4 }{ 7 } \)

The denominator is 7.

Take the number line and divide it into 7 equal parts.

First, take 1 part out of 7 parts because the first fraction is \(\frac { 1 }{ 7 } \) on a number line.

Add 4 parts from the first part out of 7 parts because the second fraction is \(\frac { 4 }{ 7 } \) on a number line.

\(\frac { 1 }{ 7 } +\frac { 4 }{ 7 } =\frac { 5 }{ 7 } \)

Finally, the final output is \(\frac { 5 }{ 7 } \).

### How to Subtract Fractions using a Fraction Number Line?

- Take the number line and divided it into equal parts.
- Divide the line into n equal parts where n is the denominator of the fraction.
- Take the two numerator numbers on a number line.
- Then, subtract the small number from a large number.
- Finally, write the numerator and denominator to get the final answer.

### Subtraction of Fractions using a Number Line Examples

**Example 1.
**Find the difference between \(\frac { 8 }{ 10 } \) and \(\frac { 6 }{ 10 } \)

**Solution: **

Given fractions are \(\frac { 8 }{ 10 } \) – \(\frac { 6 }{ 10 } \)

The denominator is 10.

Take the number line and divide it into 10 equal parts.

Find out the numerators on a number line 8 and 6.

Subtract 6 from the 8 on a number line. Then, you will get 2.

So, \(\frac { 8 }{ 10 } – \frac { 6 }{ 10 } =\frac { 2 }{ 10 } \)

The remaining part on the number line after subtraction is \(\frac { 2 }{ 10 } \).

Finally, the final output is \(\frac { 2 }{ 10 } \).

**Example 2.
**Find the difference between \(\frac { 4 }{ 5 } \) and \(\frac { 1 }{ 5 } \)

**Solution: **

Given fractions are \(\frac { 4 }{ 5 } \) – \(\frac { 1 }{ 5 } \)

The denominator is 10.

Take the number line and divide it into 5 equal parts.

Find out the numerators on a number line 4 and 1.

Subtract 1 from the 4 on a number line. Then, you will get 4 – 1 = 3.

So, \(\frac { 4 }{ 5 } – \frac { 1 }{ 5 } =\frac { 3 }{ 5 } \)

The remaining part on the number line after subtraction is \(\frac { 3 }{ 5 } \).

Finally, the final output is \(\frac { 3 }{ 5 } \).

**Example 3.**

Find the difference between \(\frac { 5 }{ 7 } \) and \(\frac { 2 }{ 7 } \)

**Solution: **

Given fractions are \(\frac { 5 }{ 7 } \) – \(\frac { 2 }{ 7 } \)

The denominator is 7.

Take the number line and divide it into 7 equal parts.

Find out the numerators on a number line 5 and 2.

Subtract 2 from the 5 on a number line. Then, you will get 5 – 2 = 3.

So, \(\frac { 5 }{ 7 } – \frac { 2 }{ 7 } =\frac { 3 }{ 7 } \)

The remaining part on the number line after subtraction is \(\frac { 3 }{ 7 } \).

Finally, the final output is \(\frac { 3 }{ 7 } \).
