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 \( \frac{7}{2} \) + \( \frac{7}{10} \)?
| 4\(\frac{1}{5}\) | |
| \( \frac{1}{10} \) | |
| 2 \( \frac{6}{13} \) | |
| \( \frac{7}{15} \) |
