To solve the expression:

\[
\frac{2}{7} + \frac{3}{14} + \frac{3}{7}
\]

### Step 1: Find the least common denominator (LCD)

The denominators are 7 and 14. The LCD of 7 and 14 is 14.

### Step 2: Rewrite fractions with the LCD

- \(\frac{2}{7}\) can be rewritten as \(\frac{4}{14}\) (because \(2 \times 2 = 4\)).
- \(\frac{3}{14}\) remains as it is.
- \(\frac{3}{7}\) can be rewritten as \(\frac{6}{14}\) (because \(3 \times 2 = 6\)).

Now, the expression is:

\[
\frac{4}{14} + \frac{3}{14} + \frac{6}{14}
\]

### Step 3: Add the numerators

\[
\frac{4 + 3 + 6}{14} = \frac{13}{14}
\]

### Final Answer:
\[
\frac{13}{14}
\]
