Hi,         

Let x represent how much gasoline will he need to travel 528 miles

Question Sets Up the Proportion

  5.25gal+%2F+231mi+=+x%2F528mi

Cross multiply to solve for x

   231x = 5.25*528

      x = 5.25*528/231

      x = 12 gal, the amount of gasoline he needs to travel 528 miles

CHECKING our Answer

5.25gal / 231mi = .0227 =   12/528mi
