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 \( \frac{4}{8} \) + \( \frac{6}{10} \)?
| 2 \( \frac{7}{16} \) | |
| 2 \( \frac{9}{40} \) | |
| 1\(\frac{1}{10}\) | |
| \( \frac{3}{40} \) |
