How do you compare ratios with different units?
If the two quantities you are comparing have different units of measure, this kind of ratio is called a rate. A rate is in the form of a unit rate when the denominator is 1. ratio as a unit rate, divide the numerator and denominator by the same number to rewrite the ratio as a fraction with a denominator of 1.
What is a ratio between two different units?

How is a ratio different from a unit?
Ratios have no units. A ratio is how many times bigger one thing is than another. It’s a number you multiply by to get one thing from another. But remember, when you find the ratio of two quantities, they must be in the same units. It’s easy to get ratios backwards
When to use ratios, rates, and proportions?
Ratios and Rates RATIOS are used, typically, to compare two like quantities. For example, if there are 13 males and 17 females, then the ratio of males to females is 13 to 17. How to write a ratio.
