Question

If a models barn door is 2 and 1 quarter inches high , how high is the actual barn door ?

Answer 1

The easiest way to solve this is to use a proportion
but first, make the 2 1/4 into a decimal. 1/4 equals .25

`(2.25)/(x) = (1)/(48)`

use butterfly method or cross mulitply to solve.
[tex]1*x=2.25*48

x=108

the barn door in real life is 108 inches
