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 \( \frac{7}{4} \) + \( \frac{8}{6} \)?
| 1 \( \frac{1}{6} \) | |
| 3\(\frac{1}{12}\) | |
| 1 \( \frac{2}{9} \) | |
| 1 \( \frac{2}{12} \) |
