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 \( \frac{3}{4} \) + \( \frac{2}{10} \)?
| 1 \( \frac{9}{20} \) | |
| \( \frac{9}{16} \) | |
| \(\frac{19}{20}\) | |
| 2 \( \frac{5}{20} \) |
