By definition, the slope is the inclination of a line in relation to the horizontal. It can be expressed in degrees, ratios and even in percent. Therefore, you can calculate it by applying the following formula:

P%=(H/L)x100

P% is the slope expressed in percent.
H is the height (H=1.2 meters).
L is the length (L=4 meters).

When you substitute these values into the formula P%=(H/L)x100, you obtain the slope of the skateboard ramp:

P%=(H/L)x100
P%=(1.2 meter/4 meters)x100
P%=0.30x100
P%=30%
