Question

if a wall is measured to 12.2 meters and on a drawing it is measured to 3.25in, what is a wall that is 5.50in in meters?

Answer 1

3.25 / 5.5 = 12.2 / x
x = 5.5 * 12.2 / 3.25

Answer 2

12.2 meters are represented by 3.25 inches.
So 12.2/3.25 is how many meters would ONE inch represent.
Now to get how many meters are represented in 5.5 inches, just multiply times 5.5

Hope that makes it easier to grasp.

Answer 3

x = 20.65
