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 \( \frac{2}{2} \) + \( \frac{4}{10} \)?
| 2 \( \frac{8}{10} \) | |
| \( \frac{8}{11} \) | |
| 1\(\frac{2}{5}\) | |
| \( \frac{1}{10} \) |
