8 members of a bridal party need transported to a wedding reception but there are only 3 2-passenger taxis available to take them. How many will need to find other transportation?
| 8 | |
| 2 | |
| 3 | |
| 4 |
There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 8 people needing transportation leaving 8 - 6 = 2 who will have to find other transportation.
This property states taht the order of addition or multiplication does not mater. For example, 2 + 5 and 5 + 2 are equivalent.

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.
Simplify \( \frac{16}{52} \).
| \( \frac{5}{11} \) | |
| \( \frac{4}{13} \) | |
| \( \frac{7}{16} \) | |
| \( \frac{1}{3} \) |
To simplify this fraction, first find the greatest common factor between them. The factors of 16 are [1, 2, 4, 8, 16] and the factors of 52 are [1, 2, 4, 13, 26, 52]. They share 3 factors [1, 2, 4] making 4 their greatest common factor (GCF).
Next, divide both numerator and denominator by the GCF:
\( \frac{16}{52} \) = \( \frac{\frac{16}{4}}{\frac{52}{4}} \) = \( \frac{4}{13} \)

An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.
What is \( \sqrt{\frac{25}{9}} \)?
| \(\frac{2}{9}\) | |
| 1\(\frac{2}{3}\) | |
| \(\frac{2}{3}\) | |
| 1\(\frac{4}{5}\) |
To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:
\( \sqrt{\frac{25}{9}} \)
\( \frac{\sqrt{25}}{\sqrt{9}} \)
\( \frac{\sqrt{5^2}}{\sqrt{3^2}} \)
\( \frac{5}{3} \)
1\(\frac{2}{3}\)
