The gradient of a road is its slope expressed as percent. What is the slope of a road with a 7% gradient?

"Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as #x/100#.

Therefore: #7% = 7/100#

The slope is therefore: #m = 7/100#

There is a rise of only #7# units along a run of #100# units.

Explanation:

The gradient or slope of a road or a line is an indication of its steepness.

This is done by comparing the vertical change against the horizontal change., often expressed as #"rise"/"run"#.

By how much does the line rise for a given horizontal distance?

If the gradient is given as #7%#, which means the same as #7/100#, it would mean a rise of only #7# units along a run of #100#.

This would be a very gentle slope.
