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 \( \frac{9}{6} \) + \( \frac{7}{10} \)?
| \( \frac{2}{10} \) | |
| 2\(\frac{1}{5}\) | |
| 1 \( \frac{6}{12} \) | |
| 1 \( \frac{1}{7} \) |
