A toy jeep is 12 1/2 inches
 Actual jeep is 18 ¾ feet long
 before we determine the ratio, let’s convert first each size into the same unit of measure and decimal points
 => 12 ½ = 25/2 
 => 12.5 inches
 => 18 ¾ = 75/4
 => 18.75 feet
 Now, let’s convert feet to inches to know the ratio
 => 1 foot = 12 inches
 => 12.5 inches : 225 inches
 => 225 / 12.5 
 => 18 inches
 thus in every 1 inch of toy car represents 1.5 feet of actual car.
