To express the relationship between the required height to length ratio and the actual height and length of the ramp, we can set up a proportion based on the given information.
The required ratio is a height-to-length ratio of 1 to 12, which can be expressed as:
\[ \frac{1}{12} \]
The ramp you mentioned has a height of 2.2 feet. We can denote the required length of the ramp (let's call it \( L \)) as follows:
Based on the ratio,
\[ \frac{\text{Height}}{\text{Length}} = \frac{2.2}{L} \]
Setting these two ratios equal to each other gives us the proportion:
\[ \frac{1}{12} = \frac{2.2}{L} \]
If you want to express it in fraction form as a proportion, you would write:
\[ \frac{1}{12} = \frac{2.2}{L} \]
This relationship shows the proportionality between the height and length of the wheelchair ramp, confirming that the actual height and length maintain the required ratio.
