A scale drawing of a building needs to be made using the scale 1 in equals = 220 ft. How tall will the building in the scale drawing be if the building is 1540 ft tall?
You divide 1540 by 220 to get 7. We do this because we want to find how many times 220 can go in 1540 which shows the amount of ft tall the scale will be. We can check it by doing 7 × 220 which is 1,540.
