Slope percentage is calculated similarly by dividing rise by run, but then multiplying by 100 to get a percentage:

e.g.:<math>slope=\left (\frac{rise}{run}\right )\times 100=\left(\frac{4\ m}{12\ m}\right)\times 100= 33\%</math>

e.g.:<math>slope=\left (\frac{rise}{run}\right )\times 100=\left(\frac{4\ m}{12\ m}\right)\times 100= 33\%</math>

For some calculations the ''rise/run'' isn't multiplied by 100, and instead is left as a decimal. e.g. 0.33 in the example above.
