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 \( \frac{4}{8} \) + \( \frac{8}{10} \)?
| 2 \( \frac{5}{40} \) | |
| 2 \( \frac{7}{40} \) | |
| 1 \( \frac{5}{13} \) | |
| 1\(\frac{3}{10}\) |
