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 \( \frac{3}{6} \) + \( \frac{3}{10} \)?
| 1 \( \frac{5}{30} \) | |
| \(\frac{4}{5}\) | |
| 2 \( \frac{4}{13} \) | |
| \( \frac{3}{10} \) |
