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 \( \frac{6}{5} \) + \( \frac{7}{9} \)?
| \( \frac{9}{45} \) | |
| 1\(\frac{44}{45}\) | |
| 1 \( \frac{2}{45} \) | |
| 2 \( \frac{1}{4} \) |
