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 \( \frac{4}{5} \) + \( \frac{9}{7} \)?
| 1 \( \frac{5}{10} \) | |
| 2 \( \frac{7}{35} \) | |
| 1 \( \frac{8}{11} \) | |
| 2\(\frac{3}{35}\) |
