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 \( \frac{5}{6} \) + \( \frac{9}{14} \)?
| 1\(\frac{10}{21}\) | |
| \( \frac{8}{42} \) | |
| 1 \( \frac{9}{18} \) | |
| \( \frac{9}{18} \) |
