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 \( \frac{5}{4} \) + \( \frac{7}{10} \)?
| 2 \( \frac{3}{20} \) | |
| \( \frac{1}{20} \) | |
| \( \frac{1}{8} \) | |
| 1\(\frac{19}{20}\) |
