Answer 3

Why is it A? like an explanation?

Answer 4

your welcome. ;D ok so it says that the building is 900 feet tall and 150 feet tall. It also says that the models height is 3 feet. So you just need to put both of the heights as the numerator and since you know it is 150 feet wide than youc an put that as the denominator and since you don't know how wide the model is taht is why you have a w in the other numerator. :)

Answer 5

oh I understand!

Answer 6

yeah so then you can just pretty much reduce the 900/150 down to 3/w to figure out what "w" is. :)
