if a fleet of n taxis uses g gallons of gasoline every 3 days, how many gallons of gasoline will be used by 4 taxis every 3 days

Question

This is a math problem, and I don't know how to solve it!

Answer 1

I think you may not have copied the entire problem; nevertheless:

 

(n/g) = (4/x) where x is the number of gallons used by 4 taxis and

x = 4g/n
