Solve the Addition: 2/5 + 2/5 Step-by-Step

To solve the problem of adding two fractions with a common denominator, we follow these steps:

• Step 1: Identify the numerators and denominators. Both fractions are $\frac{2}{5}$.
• Step 2: Since the denominators are the same, add the numerators: $2 + 2 = 4$.
• Step 3: Keep the common denominator: 5.
• Step 4: Form the result as a new fraction: $\frac{4}{5}$.

Therefore, the sum of $\frac{2}{5}$ and $\frac{2}{5}$ is $\frac{4}{5}$.

The correct choice from the provided options is $\frac{4}{5}$, which corresponds to choice 4.
