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 \( \frac{9}{2} \) + \( \frac{4}{10} \)?
| 1 \( \frac{7}{11} \) | |
| 1 \( \frac{6}{10} \) | |
| 2 \( \frac{4}{9} \) | |
| 4\(\frac{9}{10}\) |
