$$\frac{2}{7}+\frac{5}{21}\times 3$$

Express \frac{5}{21}\times 3 as a single fraction.

$$\frac{2}{7}+\frac{5\times 3}{21}$$

Multiply 5 and 3 to get 15.

$$\frac{2}{7}+\frac{15}{21}$$

Reduce the fraction \frac{15}{21} to lowest terms by extracting and canceling out 3.

$$\frac{2}{7}+\frac{5}{7}$$

Since \frac{2}{7} and \frac{5}{7} have the same denominator, add them by adding their numerators.

$$\frac{2+5}{7}$$

Add 2 and 5 to get 7.

$$\frac{7}{7}$$
