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 lenght of 26.4 feet. Us 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 formwithout reducing it to the lowest terms.

Answer 1

The required height-to-length ratio is 1 : 12.

The ramp's height-to-length ratio is 2.2 : 26.4.

Therefore, the proportion can be written as:

(1/12) = (2.2/26.4)
