# A gym teacher orders 42 tennis balls. Each package contains 3 tennis balls. Which of the following equations represents the number x of packages?

May 16, 2018

$x = \frac{42}{3}$

#### Explanation:

To find the amount of packages of tennis balls, take the total number of tennis balls and divide that number by the number of packages.

$\frac{42}{3} = 14 \text{ packages}$

$x = 42 \div 3 = 14$ or $x = \frac{42}{3} = 14$

#### Explanation:

You didn't list the possibilities, but there is only one.

$x$ is the number of packages of tennis balls.

To calculate the number of packages, divide the total number of tennis balls by the number of tennis balls in each package.

$x = \left(42 \text{tennis balls")/((3"tennis balls")/"package}\right)$

Invert the fraction and multiply.
