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 \( \frac{4}{9} \) + \( \frac{3}{15} \)?
| 1 \( \frac{9}{45} \) | |
| 2 \( \frac{7}{10} \) | |
| \(\frac{29}{45}\) | |
| \( \frac{2}{45} \) |
