Answer:

The least common denominator is 21.

Step-by-step explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, <em><u>21</u></em>, 24, 27, 30

7: 7, 14, <em><u>21</u></em>, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:

$\frac{1}{3}$ × $\frac{7}{7}$ = $\frac{7}{21}$ $\frac{3}{7}$ × $\frac{3}{3}$ = $\frac{9}{21}$
