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 \( \frac{5}{8} \) + \( \frac{4}{10} \)?
| 1\(\frac{1}{40}\) | |
| 1 \( \frac{4}{40} \) | |
| 1 \( \frac{2}{40} \) | |
| 1 \( \frac{2}{9} \) |
