Explanation:

Find a common denominator

$$ \text{LCD}(9, 6) = 18 $$

Convert fractions to equivalent fractions

$$ \frac{7}{9} = \frac{7 \times 2}{9 \times 2} = \frac{14}{18} $$

$$ \frac{1}{6} = \frac{1 \times 3}{6 \times 3} = \frac{3}{18} $$

Subtract the numerators

$$ \frac{14}{18} - \frac{3}{18} = \frac{14 - 3}{18} = \frac{11}{18} $$

Answer:

Subtract.

$$ \frac{7}{9} - \frac{1}{6} = $$
