In subtraction of fractions having the same denominator, we just need to subtract the numerators of the fractions.

Follow the steps of subtraction of like fractions:

We can subtract in a similar way. 7/8 of the class are boys.

3/8 of the class are girls. By how much fraction are the boys more?

**Boys 7/8**

**Girls 3/8**

7/8 - 3/8

= (7 - 3)/8

= 4/8

The difference is 4/8 or 1/2

We can also reduce the fraction to the lowest term.

4/8 ÷ 4/4

= 1/2

Examples of subtracting fractions with the same denominator:

**1.** Subtract 3/8 from 7/8**Solution:**

7/8 – 3/8

= (7 - 3)/8

= 1/2

**2.** Subtract 5/6 from 11/6**Solution:**

11/6 – 5/6

= (11 - 5)/6

= 6/6

= 1/1

= 1

**3.** Subtract 7/9 from 11/9**Solution:**

11/9 – 7/9

= (11 - 7)/9

= 4/9

**4.** Subtract 4/6 from 16/6**Solution:**

16/6 – 4/6

= (16 - 4)/6

= 2/1

= 2

**5.** Subtract 2/4 from 17/4**Solution:**

17/4 – 2/4

= (17 - 2)/4

= 15/4
