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 \( \frac{9}{6} \) + \( \frac{2}{10} \)?
| 1 \( \frac{3}{12} \) | |
| 1 \( \frac{7}{30} \) | |
| 1 \( \frac{8}{13} \) | |
| 1\(\frac{7}{10}\) |
