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 \( \frac{9}{4} \) + \( \frac{8}{6} \)?
| 3\(\frac{7}{12}\) | |
| 2 \( \frac{4}{7} \) | |
| 2 \( \frac{9}{13} \) | |
| \( \frac{9}{12} \) |
