100 feet vertically = 100 is our rise.
oveeeeeeeeeeeeeeeeeeeeeeeeeeeer
1250 feet horizontally= 1250 is our run

Grade = Rise/Run
%Grade = Rise/Run(100)

Grade = 100/1250
%Grade = 100/1250(100)

Grade = 10/125
%Grade = 0.08(100)

Grade = 2 / 25
%Grade = 8
So therefore,  the grade of the road is 2 / 25 or 0.08
And the %Grade of the road is 8.
