3/5

2/5 + 1/5

The denominator is the same, so we add the numerators

3/5

3/5

Step-by-step explanation:

We need to add the two fractions 2/5 and 1/5.

First, see if we need to find their common denominator: they both have a denominator of 5, so we're all set there!

Now, just add the numerators together:

2/5 + 1/5 = (2 + 1)/5 = 3/5

The denominator will stay 5 (don't add the 5's together).

The final answer is thus 3/5.
