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 \( \frac{6}{3} \) - \( \frac{2}{5} \)?
| 1 \( \frac{2}{15} \) | |
| \( \frac{1}{15} \) | |
| 1\(\frac{3}{5}\) | |
| \( \frac{9}{12} \) |
