AL=Actual Length=16 feet
DL=Drawn Length=4 inches
Scale=AL/DL (units must have same dimension, i.e. feet and feet, not feet and inches)
First change DL units to feet:
Note numerator and denominator of conversion factor are equivalent, so we are multiplying by 1, which does not change the value.
Divide out the inches
Simplify
Scale =AL/DL=16 feet/1/3 foot=48 Note: Scale has no units
ANSWER Vivian's drawing scale is 48:1
