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 \( \frac{3}{8} \) + \( \frac{7}{10} \)?
| 1 \( \frac{4}{9} \) | |
| \( \frac{4}{40} \) | |
| 1\(\frac{3}{40}\) | |
| 1 \( \frac{3}{40} \) |
