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 \( \frac{7}{2} \) - \( \frac{4}{6} \)?
| 2 \( \frac{2}{5} \) | |
| 1 \( \frac{4}{6} \) | |
| 2\(\frac{5}{6}\) | |
| 1 \( \frac{1}{6} \) |
