Oh no! That was incorrect!

When rates are expressed as a quantity of 1, such as 2 metres per second or 5 kg per bag, they are called unit rates.

For example, if you spend 80 dollars on 8 movie tickets, how much does one movie ticket cost?

We will write the numbers in the question as a ratio
80:8

Now divide both sides by 8 so the quantity becomes 1.
80/8 : 8/8
That will be 8:1, which means $8 per movie ticket.
