Answer:

$\frac{16}{21}$

Explanation:

Step1: Find common - denominator

The common denominator of 7 and 3 is 21.

Step2: Rewrite fractions

$\frac{3}{7}=\frac{3\times3}{7\times3}=\frac{9}{21}$ and $\frac{1}{3}=\frac{1\times7}{3\times7}=\frac{7}{21}$.

Step3: Add fractions

$\frac{9}{21}+\frac{7}{21}=\frac{9 + 7}{21}=\frac{16}{21}$.
