If there were a total of 350 raffle tickets sold and you bought 7 tickets, what's the probability that you'll win the raffle?
| 2% | |
| 18% | |
| 9% | |
| 8% |
You have 7 out of the total of 350 raffle tickets sold so you have a (\( \frac{7}{350} \)) x 100 = \( \frac{7 \times 100}{350} \) = \( \frac{700}{350} \) = 2% chance to win the raffle.
What is \( \frac{4}{7} \) x \( \frac{2}{8} \)?
| 1\(\frac{1}{7}\) | |
| \(\frac{1}{7}\) | |
| \(\frac{8}{49}\) | |
| \(\frac{1}{28}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{7} \) x \( \frac{2}{8} \) = \( \frac{4 x 2}{7 x 8} \) = \( \frac{8}{56} \) = \(\frac{1}{7}\)

The greatest common factor (GCF) is the greatest factor that divides two integers.
4! = ?
5 x 4 x 3 x 2 x 1 |
|
4 x 3 |
|
4 x 3 x 2 x 1 |
|
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.
