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 \( \frac{2}{8} \) - \( \frac{8}{10} \)?
| 1 \( \frac{3}{10} \) | |
| 2 \( \frac{8}{11} \) | |
| -\(\frac{5}{9}\) | |
| 1 \( \frac{2}{11} \) |
