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 can be written as:
$\frac{x}{1} = \frac{80}{20}$

Simplifying the right side of the equation:
$\frac{x}{1} = 4$

Cross multiplying, we have:
$x = 4$

Therefore, an employee must work 4 hours to make $80.
