Question
If you build a skateboard ramp whose ratio of height to base must be 2:3, what is the base if the height is 5m?

The height goes with the 2, and the base goes with 3.
Ratios can also be written as fractions. Just set up a simple equation and solve.
2/3 = 5/b
Cross multiply. 2*b=5*3
2b=15.
Divide by 2 to isolate b.
b=15/2 or 7.5m
