Solve the Fraction Addition: 3/7 + 1/7 Step-by-Step

To solve this problem of adding fractions with like denominators, we will follow these steps:

• Step 1: Identify and confirm that the denominators of both fractions are the same. Here, both fractions have the denominator $7$.
• Step 2: Add the numerators of both fractions: $3 + 1 = 4$.
• Step 3: Keep the common denominator, which is $7$.
• Step 4: Write the resultant fraction as $\frac{4}{7}$.

Therefore, the sum of $\frac{3}{7}$ and $\frac{1}{7}$ is $\frac{4}{7}$.
