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 \( \frac{7}{5} \) + \( \frac{6}{9} \)?
| 2 \( \frac{7}{45} \) | |
| 1 \( \frac{4}{45} \) | |
| 2\(\frac{1}{15}\) | |
| 2 \( \frac{6}{45} \) |
