Slope gradients are expressed as Y:X where Y is a single unit of rise and X is the corresponding run. It can be calculated by dividing the rise by the run:

Slope gradients are expressed as Y:X where Y is a single unit of rise and X is the corresponding run. It can be calculated by dividing the rise by the run:

e.g.:<math>\frac{rise}{run}=\frac{4\ m}{12\ m}=3</math> slope=1:3

e.g.:<math>\frac{rise}{run}=\frac{4\ m}{12\ m}=\frac{1}{3};\ so we say the slope=1:3 or 1 in 3</math>
