To solve \( \frac{7}{10} + \frac{2}{15} \), we need to find a common denominator.

### Step 1: Find the Least Common Denominator (LCD)
The denominators are 10 and 15. The least common denominator of 10 and 15 is 30.

### Step 2: Rewrite each fraction with the LCD as the denominator
- \( \frac{7}{10} = \frac{7 \times 3}{10 \times 3} = \frac{21}{30} \)
- \( \frac{2}{15} = \frac{2 \times 2}{15 \times 2} = \frac{4}{30} \)

### Step 3: Add the fractions
Now, add the numerators:
\[
\frac{21}{30} + \frac{4}{30} = \frac{21 + 4}{30} = \frac{25}{30}
\]

### Step 4: Simplify the fraction
\[
\frac{25}{30} = \frac{5}{6}
\]

So, \( \frac{7}{10} + \frac{2}{15} = \frac{5}{6} \).
