4! = ?
4 x 3 |
|
3 x 2 x 1 |
|
4 x 3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
What is \( \frac{4}{6} \) x \( \frac{2}{5} \)?
| 1\(\frac{1}{3}\) | |
| \(\frac{4}{15}\) | |
| 1\(\frac{3}{5}\) | |
| \(\frac{8}{25}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{6} \) x \( \frac{2}{5} \) = \( \frac{4 x 2}{6 x 5} \) = \( \frac{8}{30} \) = \(\frac{4}{15}\)
