Okay, a proportion is hmmmm I'm trying to think of how to explain this. It's something that normally compares two things that are either part to whole or part to part. For this particular problem, you'd set one up comparing height of the figure, to how long the shadow is.

the tree is 49 feet tall

So you'd have \(\large\tt \frac{height~of~kangaroo}{length~of~kangaroo~shadow}= \frac{height~of~tree}{length~of~tree~shadow}\)

I don't know why the spacing didn't work. :/

But how do u exactly solve this?

my picture!

Well, first plug in your values. They have to match up

After you set up your proportion, you cross multiply and divide.

I'll explain once you come up with the proportion.

yeah math

What is the other proportion on the other side is it 35/7 cause the denominator stays the same?

I don't understand what you're asking :/ What are you confused about?

  • anonymous
Is 5/7 the first step right?
BloomLocke367
  • BloomLocke367
Given the model I gave you, you should have: \(\huge\frac{5}{7}=\frac{?}{35}\)
anonymous
  • anonymous
Ok yea
BloomLocke367
  • BloomLocke367
You're trying to find the missing piece. To do that, you cross multiply 5 and 35 and then you take that product and divide it by 7.

  • anonymous
I got 25
BloomLocke367
  • BloomLocke367
Correct! Great job. Do you understand now?

Yes thank you so much I had problems with cross multiplying I get be4 wait so 25 is the numerator and 35 is the denominator?
