Question

Susie is a fast-food worker that made 28 cheeseburgers in 4 hours. a couple of days later, she made 42 cheeseburgers at the same ratio. Write an equation that represents the situation. How many hours did it take her to make 42 cheeseburgers?

Answer 1

It took her 6 hours

Explanation:

28 burgers in 4 hours means 7 burgers per hour

^To do this divide 28/4 by 4/4 which equals 7/1

To find how long it took her to make 42 burgers, you must multiply both the numerator and denominator by 6(since 7*6=42)

So, 42/1 divided by 7/1 equals 6 hours
