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 \( \frac{9}{5} \) - \( \frac{5}{7} \)?
| 1 \( \frac{9}{35} \) | |
| 2 \( \frac{8}{12} \) | |
| \( \frac{4}{11} \) | |
| 1\(\frac{3}{35}\) |
