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 \( \frac{2}{6} \) + \( \frac{7}{10} \)?
| \( \frac{4}{30} \) | |
| 2 \( \frac{8}{16} \) | |
| 1\(\frac{1}{30}\) | |
| 1 \( \frac{6}{11} \) |
