Using three variables, create (make up) an equation. After you have made your equation, solve it 3 different times. You will end with three answers all solved for different variables. For example, 5c/f=1/r, solve for r, c and f. Show all of your steps.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
