From a base elevation of 6300 ft. a mountain peak rises to a summit elvation of 14366 ft. over a horizontal distance of 15844 ft. Find the grade of the peak. The grade of the peak is ?%I do not even know where to begin with this.

Does the 6300 ft.get subtracted from 14366 and from 15844 and if so that leaves me with 8066/9584. If this is correct how do I change it to a %? I am so lost
