If there were a total of 300 raffle tickets sold and you bought 9 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 17% | |
| 3% | |
| 8% |
You have 9 out of the total of 300 raffle tickets sold so you have a (\( \frac{9}{300} \)) x 100 = \( \frac{9 \times 100}{300} \) = \( \frac{900}{300} \) = 3% chance to win the raffle.
Solve 5 + (5 + 2) ÷ 4 x 5 - 32
| 4\(\frac{3}{4}\) | |
| 1\(\frac{1}{2}\) | |
| \(\frac{5}{6}\) | |
| \(\frac{5}{9}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
5 + (5 + 2) ÷ 4 x 5 - 32
P: 5 + (7) ÷ 4 x 5 - 32
E: 5 + 7 ÷ 4 x 5 - 9
MD: 5 + \( \frac{7}{4} \) x 5 - 9
MD: 5 + \( \frac{35}{4} \) - 9
AS: \( \frac{20}{4} \) + \( \frac{35}{4} \) - 9
AS: \( \frac{55}{4} \) - 9
AS: \( \frac{55 - 36}{4} \)
\( \frac{19}{4} \)
4\(\frac{3}{4}\)
What is \( \frac{2}{7} \) x \( \frac{1}{9} \)?
| \(\frac{2}{21}\) | |
| \(\frac{1}{48}\) | |
| \(\frac{2}{9}\) | |
| \(\frac{2}{63}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{2}{7} \) x \( \frac{1}{9} \) = \( \frac{2 x 1}{7 x 9} \) = \( \frac{2}{63} \) = \(\frac{2}{63}\)
