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 \( \frac{4}{2} \) + \( \frac{2}{6} \)?
| 1 \( \frac{9}{18} \) | |
| 2\(\frac{1}{3}\) | |
| 2 \( \frac{3}{12} \) | |
| 2 \( \frac{1}{6} \) |
