Activity 1

In this activity, you will convert the actual height of skyscrapers or the actual length of bridges and tunnels into a reduced scale of inches. The scale you will use is 50 feet  = 1inch; this is the ratio of 50/1.  Round all answers to the nearest hundredth.  To find the actual height or length, click on the name of the structure. Remember to keep the order of the terms the same in both proportions.
