What is \( \frac{1}{5} \) x \( \frac{3}{6} \)?
| \(\frac{3}{5}\) | |
| \(\frac{4}{45}\) | |
| \(\frac{2}{21}\) | |
| \(\frac{1}{10}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{5} \) x \( \frac{3}{6} \) = \( \frac{1 x 3}{5 x 6} \) = \( \frac{3}{30} \) = \(\frac{1}{10}\)
