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

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.

$\frac{42}{3} = 14 packages$ $42/3=14" packages"$

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

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

$x$ $x$ 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.

$x = \frac{42 tennis balls}{\frac{3 tennis balls}{package}}$ $x=(42"tennis balls")/((3"tennis balls")/"package")$

Invert the fraction and multiply.
