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 \( \frac{4}{5} \) + \( \frac{2}{7} \)?
| \( \frac{2}{9} \) | |
| \( \frac{9}{16} \) | |
| 1\(\frac{3}{35}\) | |
| 1 \( \frac{7}{35} \) |
