We will use the ratio and proportion method ( an equation formed with two ratios that are equal) to solve the question “if it takes 18 gallons of gas to go 400 miles,  how many gallons would it take to go 300 miles?” Let x= the number of gallons for the gas  to go 300 miles 18:400=X:300400x=300*18400x=5400X=5400/400X=13.5 so the answer is B.
