A company pays their employees $20 per hour. Using fractional notation, write a proportion that represents how long an employee must work to make $80. Use x to represent the unknown number of hours.

Answer 1

The proportion that represents how long an employee must work to make $80 is:

$\frac{x}{80} = \frac{1}{20}$.

This can also be written as:

$x/80 = 1/20$.
