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 \( \frac{3}{4} \) + \( \frac{4}{12} \)?
| 1\(\frac{1}{12}\) | |
| \( \frac{9}{16} \) | |
| \( \frac{8}{15} \) | |
| \( \frac{9}{15} \) |
