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 \( \frac{4}{9} \) + \( \frac{6}{15} \)?
| \( \frac{8}{16} \) | |
| 2 \( \frac{3}{45} \) | |
| 1 \( \frac{3}{6} \) | |
| \(\frac{38}{45}\) |
