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 \( \frac{7}{4} \) + \( \frac{5}{10} \)?
| \( \frac{8}{14} \) | |
| 2 \( \frac{3}{10} \) | |
| 2 \( \frac{6}{20} \) | |
| 2\(\frac{1}{4}\) |
