Answer:

21:4

Step-by-step explanation:

You must use the same units. Let's convert the length of the car to inches since the length of the model is given in inches.

7 ft * (12 inches)/(1 ft) = 84 inches

ratio of length of car to length of model = 84/16 = 21/4 = 21:4

So you have to convert feet into inches= 7 x 12= 84 inches

so the length of the car is 84 inches

now length of model is 16 inches, therefore the ratio of the length of the car to the model is

[tex] \frac{84}{16} = \frac{21}{4} [/tex]

ans: 21/4
