John's car is 13 feet long. He is making a model that is 1/12 of the actual size. Which proportion below should be used to find the length, L, of the model?

A(wrong) 13/L = 1/12
B(correct) L/13 = 1/12
C(wrong) L/13 = 1/L
D(wrong) 12/L = 13/1

I don't get it! How is it B?

  • Math -

    let the model length be L

    Does it not say "John's car is 13 feet long. He is making a model that is 1/12 of the actual size" ??

    which translates to L = (1/12)13
    divide both sides by 13 and you get
    L/13 = 1/12

    mmmhhh?
