Fractions must share a common denominator in order to be added or subtracted. The common denominator is the least common multiple of all the denominators.
What is \( \frac{9}{4} \) + \( \frac{9}{6} \)?
| 2 \( \frac{5}{12} \) | |
| 2 \( \frac{3}{11} \) | |
| 3\(\frac{3}{4}\) | |
| \( \frac{4}{12} \) |
