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?

Reiny
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?
