Question

If you rent 5 dvds for 5 nights for $5, at this rate how much do you expect to pay for 1 dvd for 1 night?

Answer 1

20 cents a night because 5 DVDs per night is 1 dollar, and $1/5 DVDs equals 20 cents each, so 1 DVD is 20 cents a night

Answer 2

It would be 1$ for one DVD each night.

5 DVD per 5 nights = 5$

thus, 5/5 DVD per 5/5 nights = 5/5$      (balancing LHS and RHS)

= 1 DVD per night for 1 $
