Quizplus · Accepted Answer

Convert the mixed numbers to improper fractions: $18 \frac{3}{6} = 18.5 = \frac{37}{2}$ and $11 \frac{2}{30} = 11.0667 = \frac{332}{30}$. Find a common denominator (30), convert $\frac{37}{2}$ to $\frac{555}{30}$, and subtract: $\frac{555}{30} - \frac{332}{30} = \frac{223}{30}$. Convert back to a mixed number: $7 \frac{13}{30}$.
