3 inches

convert 5 feet to inches

5ft= 60in

proportion of the big tires is 60:8 or 15:2

the small tire on the toy model is unknown but the small tires on the actual model is 3ft and 9 in

convert that to inches as well

3ft and 9in= 45 inches

45÷15= 3 (this is to see how many times the x (15) increases so that we can equally increase the y value

3x2= 6

hope this helped!

Answer:

  6 in

Step-by-step explanation:

The sizes are proportional, so you have ...

  toy size / actual size = (8 in)/(5 ft) = x/(3.75 ft)

Multiply by 3.75 ft to get ...

  x = (8 in)(3.75/5) = (8 in)(0.75) = 6 in

The small tire on the toy is 6 inches in diameter.

__

3 ft 9 in = 3 9/12 ft = 3.75 ft
