Question
How would you find the scale factor of a drawing that shows a length of 4 inches when the actual object is 8 feet long?

A.Use the given lengths, form a scale, and then simplify.

B.Convert one of the lengths into the same units as the other length. Then, form a scale and simplify.


C.Multiply the given lengths, then simplify.

D.Add the given lengths, then divide by 12 and simplify.

Answer 1

A

Explanation:

`(4in)/(8ft)` =
`(1in)/(2ft)`

1in:2ft

1ft = 12in

Scale factor=
`(1in)/(24in)`

Scale factor 1:24
