the sears tower of Chicago is 1450 feet high. a model is 24 inches tall. what is the ratio of the height of the model to the height of the actual sears tower?
Def scale is 1:x where x is actual size Note 1 doesn't always work for numbers given, but is preferred
24:1450 -> 24/1450 Let's do it step by step of easiest factor to find An obvious one is 2 24/1450 = 12/725 Can't be simplified Thus the scale is 12:725 But if 1:x is required we divide it out to get 12:725 is about 1:0.0166 Actual number is irrational and goes on forever
