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 \( \frac{9}{8} \) + \( \frac{2}{10} \)?
| 1\(\frac{13}{40}\) | |
| 2 \( \frac{5}{11} \) | |
| 1 \( \frac{2}{6} \) | |
| 1 \( \frac{6}{15} \) |
