    The scale model of a skyscraper is 4,3 feet tall. When it is finished, the skyscraper will be 525 meters tall. What Cale was used to make the model. Please show work so I can figure out similar questions.

    First of all you need to be working with everything in the same units, so either convert ft to m or vice versa. 1 ft is 0,3048 meters, so 4,3 ft*0,3048 m/ft=1,31064 mThe scale is the size of the model divided by the size of the real thing. If 1 cm in a map represents 100 m in real life, then considering 100 m are 10,000 cm, the scale would be 1:10,000In this problem it's the same, you need to find the proportion between the model and the building, which would be 1,31064:525. Or if you divide by the smallest number, 1:400,57If you work with feet instead of meters, 525 m=1772,44094 m. So the scale would be 4,3:1772,44094, which if you divide by 4,3 is 1:412,2
