Addition of Fifth Fractions: Finding the Sum of 1/5 and 2/5

To solve the problem of adding $\frac{1}{5}$ and $\frac{2}{5}$, follow these steps:

Step 1: Identify the denominators

Both fractions, $\frac{1}{5}$ and $\frac{2}{5}$, have the common denominator of 5. This simplifies the addition process since we only need to add the numerators.

Step 2: Add the numerators

When adding fractions with the same denominator, keep the denominator unchanged:

$\frac{1}{5} + \frac{2}{5} = \frac{1 + 2}{5}$

Step 3: Perform the addition

Add the numerators: $1 + 2 = 3$. So, the sum is:

$\frac{3}{5}$

Therefore, the solution to the problem is $\frac{3}{5}$.
