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 \( \frac{9}{5} \) + \( \frac{8}{9} \)?
| 1 \( \frac{1}{9} \) | |
| 2\(\frac{31}{45}\) | |
| 2 \( \frac{2}{45} \) | |
| 2 \( \frac{3}{10} \) |
