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