Answer in decimal form: 4.5 inches
Answer as a mixed number = 4 & 1/2 inches
========================================================
Explanation:
" It has a scale of 1 inch for every 32 inches on a real-sized truck" means the the scale is 1:32
Put another way, the real life width is 32 times greater than the scale model.
So we can form the equation
y = 32x
where x is the scale model width and y is the actual real life width.
---------
The garage in the real world is 12 feet wide, or 12*12 = 144 inches wide.
Plug y = 144 into the equation and solve for x
y = 32x
32x = y
32x = 144
x = 144/32
x = 4.5
His scale model garage must be 4.5 inches wide
4.5 inches = 4 & 1/2 inches = 4 and a half inches
