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 \( \frac{3}{3} \) + \( \frac{8}{7} \)?
| 2\(\frac{1}{7}\) | |
| 2 \( \frac{9}{12} \) | |
| \( \frac{7}{14} \) | |
| 1 \( \frac{3}{21} \) |
