Question from Kenneth:

Hello:

Can you think of a ratio that has units that have not canceled out?
Do not use a rate as an example, for example miles per hour.

Would the following make sense? What is the book to student ratio in
a classroom with 20 students and 15 books? Student to book ratio of
20 students to 15 books or (4 students):(3 books).

I thank you for your reply.

HI Kenneth,

Your example is fine. Also how about this?

Sam worked for 8 hours and made $\$120.00$ so the ratio of dollars per hour is

120:8 or 15 (dollars) : 1 (hour).
