What's an 8% grade of a ramp?

  1. 1. The problem statement, all variables and given/known data
    An automobile driver travelling down an 8% grade slams on his breaks and skids 26 m until hitting a car...

    2. Relevant equations

    3. The attempt at a solution
    I have no idea what a 8% grade is. I am guessing it is a slope, but how much?

    Thanks for any help I am stumped.
