"What does that mean?" - No offense, but I think it means you need
to go back to your math teacher and explain that you don't understand
the problem.
A ratio is a fraction, in this case it is dealing with a slope, so
think of it as "rise over run". How far up (or down) does the slope
change over the distance it goes. 1:12 will go up 1 inch for every
12 inches or 1 foot for every 12 feet or 1 mile for every 12 miles.
In your case, it will go up 1 meter for every 12 meters.
10 x 1:12 = 10 x 1/12
