Question

A model of a building was built to a scale of 1:65.5. One side of the model is 23 inches long. How long, in feet, is this side of the actual building? Round your answer to the nearest tenth.

Answer 1

130ft: you would need to do 65.5 x 23 to get 1506.5 but this is in inches, not ft so you need to convert this, which means that you need to divide 1506.5 by 12 which gets 125.54..... and round that to the nearest tenth, which leaves you with 130ft

hope this helps
