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 \( \frac{6}{4} \) + \( \frac{6}{10} \)?
| \( \frac{9}{20} \) | |
| 1 \( \frac{1}{7} \) | |
| 2\(\frac{1}{10}\) | |
| 1 \( \frac{6}{20} \) |
