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 \( \frac{7}{2} \) + \( \frac{4}{10} \)?
| 3\(\frac{9}{10}\) | |
| \( \frac{1}{10} \) | |
| 2 \( \frac{8}{10} \) | |
| \( \frac{8}{17} \) |
