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 \( \frac{2}{3} \) + \( \frac{4}{5} \)?
| \( \frac{7}{10} \) | |
| 1\(\frac{7}{15}\) | |
| 2 \( \frac{9}{15} \) | |
| \( \frac{7}{15} \) |
