Answer:

3 inches

Step-by-step explanation:

Hello!
We can set up a proportion: [tex]\frac{\frac{1}{2}}{\frac16}} = \frac{x}{1}[/tex]

(Check the last answer for information on setting up proportions)

Solve:

  • Cross multiply the terms:
    1/2 = 1/6x
  • Multiply both sides by 6 to remove the unit rate:
    1/2 * 6 = 1x
  • Simplify:
    3 = x

1 yard in real life is 3 inches on the model.
  • 1/2 inch represents 1/6yard

1 yard represent:

  • 1/2/(1/6)
  • 1/2(6)
  • 3in
