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 \( \frac{4}{3} \) - \( \frac{9}{5} \)?
| 2 \( \frac{9}{15} \) | |
| 2 \( \frac{6}{15} \) | |
| -\(\frac{7}{15}\) | |
| \( \frac{8}{13} \) |
