A house has 6 stories, each the same height. How many times as long is the ascent to the sixth floor as the ascent to the third?
To reach the 3rd floor, you will need to climb the stairs 2 times. From 1st to 2nd story and then from 2nd to 3rd story.
To reach the 6th floor, you will need to climb the stairs 5 times. So, the answer is 5/2, not 6/3.
