A wheelchair ramp requires a minimum 1:12 ratio of height to length, meaning a ramp with a height of 2.2 feet requires a length of 26.4 feet. Use a proportion to describe the relationship between the required height-to-length ratio and the ramp’s height-to-length ratio. Write the proportion in fraction form without reducing it to the lowest terms. (1 point)
Required height-to-length ratio: 1:12
Ramp's height-to-length ratio: 2.2:26.4
The proportion can be written as:
(1/12) = (2.2/26.4)

Let's represent the required height-to-length ratio as "x" and the ramp's height-to-length ratio as "y".
According to the given information, the wheelchair ramp requires a minimum 1:12 ratio of height to length, which can be written as:
x : 1 = y : 12
We can cross-multiply to get:
12x = y
Therefore, the proportion in fraction form without reducing it to the lowest terms is:
12x/y = 1
To describe the relationship between the required height-to-length ratio and the ramp's actual height-to-length ratio, we can set up a proportion.
Let's denote the required height-to-length ratio as "R" and the ramp's actual height-to-length ratio as "A".
According to the given information, the required height-to-length ratio R is 1:12, meaning for every 1 unit of height, there should be 12 units of length.
The ramp's actual height-to-length ratio A can be expressed as the height of the ramp divided by its length.
Therefore, we can set up the proportion:
R: A = 1:12
Substituting the values:
1:12 = 2.2: L
Where L represents the length of the ramp.
Thus, the proportion in fraction form without reducing it to the lowest terms is:
1/12 = 2.2/L
