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 \( \frac{7}{4} \) + \( \frac{6}{12} \)?
| 1 \( \frac{2}{5} \) | |
| 2 \( \frac{1}{9} \) | |
| 2\(\frac{1}{4}\) | |
| \( \frac{8}{17} \) |
