Do it by splitting middle term.
Then you will be able to get factors . You can learn how to split middle term by searching videos on you tube or any site.
Whenever you see the word "per" you can ALWAYS substitue in the word "divide". When you see "miles per gallon", change "per" into "divided by" to get miles divided by gallons. That is how you will solve the problem.
SO.....
300 miles ÷ 10 gallons = 30 miles per gallon
