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