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 \( \frac{8}{9} \) + \( \frac{3}{15} \)?
| \( \frac{6}{9} \) | |
| \( \frac{8}{11} \) | |
| 1\(\frac{4}{45}\) | |
| 2 \( \frac{4}{45} \) |
