The greatest common factor (GCF) is the greatest factor that divides two integers.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 40% off." If Alex buys two shirts, each with a regular price of $38, how much will he pay for both shirts?
| $60.80 | |
| $15.20 | |
| $55.10 | |
| $22.80 |
By buying two shirts, Alex will save $38 x \( \frac{40}{100} \) = \( \frac{$38 x 40}{100} \) = \( \frac{$1520}{100} \) = $15.20 on the second shirt.
So, his total cost will be
$38.00 + ($38.00 - $15.20)
$38.00 + $22.80
$60.80
Solve for \( \frac{6!}{5!} \)
| \( \frac{1}{8} \) | |
| \( \frac{1}{3024} \) | |
| 6 | |
| 60480 |
A factorial is the product of an integer and all the positive integers below it. To solve a fraction featuring factorials, expand the factorials and cancel out like numbers:
\( \frac{6!}{5!} \)
\( \frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{5 \times 4 \times 3 \times 2 \times 1} \)
\( \frac{6}{1} \)

Which of these numbers is a factor of 16?
| 11 | |
| 8 | |
| 5 | |
| 4 |
The factors of a number are all positive integers that divide evenly into the number. The factors of 16 are 1, 2, 4, 8, 16.
If there were a total of 150 raffle tickets sold and you bought 6 tickets, what's the probability that you'll win the raffle?
| 12% | |
| 4% | |
| 15% | |
| 11% |
You have 6 out of the total of 150 raffle tickets sold so you have a (\( \frac{6}{150} \)) x 100 = \( \frac{6 \times 100}{150} \) = \( \frac{600}{150} \) = 4% chance to win the raffle.
