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