Question

a scale drawing of a building needs to be made using the scale 1 in = 190 ft. how tall will the builging in the scale drawing be if the building is 570 ft tall​

Answer 1

`\boxed{\text{3 in}}`

Explanation:

1 in = 190 ft

x in = 570 ft

We can use ratio and proportion to solve this problem.

`\begin{array}{cccl}(1)/(x) & = & (190)/(570) & \\\\570 & = & 190x & \text{Mutiplied by lowest common denominator (570x)}\\3 & = & x & \text{Divided each side by 3}\\\end{array}`

The building will be
`\boxed{\textbf{3 in}}` tall in the scale drawing.
