$1 \frac{2}{21}$
Work Step by Step
1. Find LCD of fractions:
The LCD of 3 and 7 is 21.
2. Write as equivalent fractions with denominator of 60.
$\frac{2*7}{3*7} + \frac{3*3}{7*3} = \frac{14}{21} + \frac{9}{21}$
3. Subtract numerators.
$\frac{14+9}{21} = \frac{23}{21} = 1 + \frac{2}{21} = 1 \frac{2}{21}$
