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 \( \frac{3}{5} \) + \( \frac{5}{7} \)?
| \( \frac{5}{35} \) | |
| 1 \( \frac{4}{8} \) | |
| 1\(\frac{11}{35}\) | |
| \( \frac{3}{10} \) |
