That number is the ratio of 578,778,777 to 100,000,000 , so it's rational.
Here's a surprising factoid:
ANY number that you can completely write down on paper with digits...
and a decimal point or a fraction bar if you need them ... is rational.
If you can write it down ... without saying "repeating" or using symbols ...
it's rational.
You take 480 and divide it by 15, because it says per gallon. so then if the car goes 480 miles with 15 gallons, you have to figure out how to find per gallon. you divide 480/15 and your answer is 32
