63/80 x 100 = 78.8%
You divide normally but multiply by 100 (moving the decimal over two places).
        
                    
             
        
        
        
You first find its intercepts: the x intercept is (5/3,0) and the y intercept is (0,5) (just plot those points). Then make the line connecting those 2 points!
