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 \( \frac{7}{8} \) + \( \frac{9}{16} \)?
| 1\(\frac{7}{16}\) | |
| \( \frac{2}{11} \) | |
| 1 \( \frac{3}{7} \) | |
| \( \frac{1}{16} \) |
