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 \( \frac{9}{5} \) + \( \frac{7}{7} \)?
| 2\(\frac{4}{5}\) | |
| \( \frac{6}{15} \) | |
| 1 \( \frac{9}{18} \) | |
| \( \frac{3}{35} \) |
