Adding Fractions − When the denominator is the same
The denominator remains the same. Just add the numerators and maybe write the fraction in its simplest form
- Example 1. 1/5 + 2/5 = 3/5
- Example 2. 1/10 + 2/10 = 3/10
- Example 3. 1/7 + 2/7 = 3/7
- Example 4. 1/3 + 2/3 = 3/3 = 1
- Example 5. 1 1/4 + 2 3/4
(a) | Convert the mixed numbers to top heavy fractions |
1 1/4 + 2 3/4 = 5/4 + 11/4 | |
(b) | Add the top heavy fractions |
5/4 + 11/4 = 16/4 = 4 |
