To describe the relationship between the required height-to-length ratio (1:12) and the ramp's height-to-length ratio when the height is 2.2 feet and the length is 26.4 feet, we can set up the following proportion.
The required ratio can be expressed as:
\[ \frac{\text{height}}{\text{length}} = \frac{1}{12} \]
The actual ratio for the ramp is:
\[ \frac{\text{height}}{\text{length}} = \frac{2.2}{26.4} \]
Now, we can set up the proportion:
\[ \frac{1}{12} = \frac{2.2}{26.4} \]
Thus, the proportion in fraction form without reducing it is:
\[ \frac{1}{12} = \frac{2.2}{26.4} \]
