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 \( \frac{4}{6} \) - \( \frac{2}{14} \)?
| 1 \( \frac{1}{10} \) | |
| 2 \( \frac{5}{11} \) | |
| \(\frac{11}{21}\) | |
| 2 \( \frac{1}{7} \) |
