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 \( \frac{5}{4} \) - \( \frac{6}{10} \)?
| 1 \( \frac{6}{20} \) | |
| 2 \( \frac{8}{11} \) | |
| 2 \( \frac{1}{20} \) | |
| \(\frac{13}{20}\) |
