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 \( \frac{5}{5} \) + \( \frac{9}{7} \)?
| 2 \( \frac{6}{12} \) | |
| 2\(\frac{2}{7}\) | |
| \( \frac{3}{35} \) | |
| \( \frac{4}{35} \) |
