Quizplus · Accepted Answer

To subtract mixed numbers, first convert them to improper fractions: $12 \frac{2}{9} = \frac{110}{9}$ and $6 \frac{5}{6} = \frac{41}{6}$. To subtract, find a common denominator, which is 54 here. So, $\frac{110}{9} = \frac{660}{54}$ and $\frac{41}{6} = \frac{369}{54}$. Subtracting gives $\frac{660}{54} - \frac{369}{54} = \frac{291}{54}$, which simplifies to $5 \frac{7}{18}$.
