Question 29936: A building has 12 floors. Each is the same height. How many times as long as the trip to the third floor is the trip to the twelfth floor?

You can put this solution on YOUR website! In this problem, it is neccessary to focus on the numbers you have been given, since each floor is the same height.
Look at the proportions between 3 and 12. By simplifying this proportion, you obtain 1 to 4. (divide by lowest common multiple)
This 1 to 4 Ratio means that it would take 4 times as long to reach the 12th floor than it would the 3rd. So look at the question your problem is asking you, if a trip to the 12th floor is 4 times longer than a trip to the third, reverse the number. This gives us 1/4. So, a trip to the 3rd floor takes 1/4 the time as a trip to the 12th floor.
I hope this helped you and answered your question.
