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 \( \frac{5}{3} \) + \( \frac{6}{7} \)?
| 1 \( \frac{1}{10} \) | |
| 2 \( \frac{4}{21} \) | |
| 2\(\frac{11}{21}\) | |
| 1 \( \frac{7}{10} \) |
