Question

What exactly are proportions?

Answer 1

Proportions are simply put as corresponding values/sizes. Many times equal, sometimes not (such as the idea of similar triangles.)
For example 3/4 is a proportion of 30/40

Answer 2

Can you simplify that? In in middle school.

Answer 3

Let me give you a real life example.

You get 25% off at a clothing store.
The item you want to buy is 200 dollars.
To solve this question you can set up a proportion, a proportion is basically the equal value.

So you want to find the money you get off.
25/100=x/200

25 of 100 is equal to 50 of 200 so this is a proportion
