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 \( \frac{2}{8} \) + \( \frac{6}{10} \)?
| 1 \( \frac{4}{10} \) | |
| \( \frac{9}{40} \) | |
| \(\frac{17}{20}\) | |
| \( \frac{6}{40} \) |
