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.

Answer 1

Let x be the height-to-length ratio of the required wheelchair ramp. The proportion can be written as x/1:12/1.
