How to find out the steepness of a slope? How to calculate gradient? (p.17)

Gradient is the ratio (比率) of the vertical distance to the horizontal distance.

Multiple Choice

Which slope is the steepest?

1:40? 1:10? 1:2? or 1:1?

• 1:40

• 1:10

• 1:2

• 1:1

Conclusion:

• The larger the gradient (1:1 > 1:40), the steeper the slope.
