Question

A scale drawing of a building needs to be made using the scale 1 in = 200 ft. How tall will the building in the scale drawing be if the building is 1200 ft tall?

Answer 1

Explanation:

Not very big.

1" = 200 feet

x = 1200 feet

1/x = 200/1200 Cross multiply

200 x = 1200 * 1 Combine

200x = 1200 Divide by 200

x = 1200 / 200

x = 6

Remark: the feet (one on each of the equal sign cancel out. All that is left is inches. So 6 is in inches.
