If a mayor is elected with 73% of the votes cast and 89% of a town's 40,000 voters cast a vote, how many votes did the mayor receive?
| 25,276 | |
| 19,580 | |
| 20,292 | |
| 25,988 |
If 89% of the town's 40,000 voters cast ballots the number of votes cast is:
(\( \frac{89}{100} \)) x 40,000 = \( \frac{3,560,000}{100} \) = 35,600
The mayor got 73% of the votes cast which is:
(\( \frac{73}{100} \)) x 35,600 = \( \frac{2,598,800}{100} \) = 25,988 votes.
The __________ is the greatest factor that divides two integers.

The greatest common factor (GCF) is the greatest factor that divides two integers.
Which of these numbers is a factor of 20?
| 4 | |
| 18 | |
| 12 | |
| 14 |
The factors of a number are all positive integers that divide evenly into the number. The factors of 20 are 1, 2, 4, 5, 10, 20.
What is \( \frac{1}{5} \) x \( \frac{4}{6} \)?
| \(\frac{4}{5}\) | |
| \(\frac{16}{63}\) | |
| \(\frac{2}{15}\) | |
| \(\frac{1}{45}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{5} \) x \( \frac{4}{6} \) = \( \frac{1 x 4}{5 x 6} \) = \( \frac{4}{30} \) = \(\frac{2}{15}\)
4! = ?
5 x 4 x 3 x 2 x 1 |
|
4 x 3 x 2 x 1 |
|
3 x 2 x 1 |
|
4 x 3 |
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.
