Solve the Fraction Addition: 1/7 + 2/7 Step-by-Step

Solve the following exercise:

$\frac{1}{7}+\frac{2}{7}=\text{?}$

To solve this problem, we'll follow these steps:

• Step 1: Identify that both fractions have the same denominator.
• Step 2: Add the numerators while keeping the denominator constant.
• Step 3: Simplify the resulting fraction if necessary.

Now, let's work through each step:
Step 1: Both fractions, $\frac{1}{7}$ and $\frac{2}{7}$, have a common denominator of 7.
Step 2: Add the numerators: $1 + 2 = 3$.
Step 3: Write the sum as a fraction with the denominator 7: $\frac{3}{7}$.

Therefore, the solution to the problem is $\frac{3}{7}$.
