Work out 1/5 + 1/5
How to approach this question
To add fractions with the same denominator, you add the numerators and keep the denominator the same.
1. The denominators are both 5.
2. Add the numerators: 1 + 1 = 2.
3. Keep the denominator: 5.
The result is 2/5.
Full Answer
2/5
When adding fractions, if the denominators (the bottom numbers) are the same, the process is straightforward. You simply add the numerators (the top numbers) together and place the sum over the common denominator.
In this case, we have 1/5 + 1/5.
The denominators are both 5.
We add the numerators: 1 + 1 = 2.
The result is 2/5.
Common mistakes
✗ A common mistake is to add the denominators as well as the numerators, resulting in 2/10. This is incorrect.
