Question

How are ratios different from fractions?

Answer 1

It is how you use it...

Explanation:

Really, fractions `"are"` another way of representing rations. However, the difference comes in how you use it.

Ratios are used to compare things like `"If there are x amount of this, then there are y amount of that"`

For example, if you have `1:2` and you are comparing the number of boys to girls, you can say that:
For every one boy, there are two girls.

A fraction represents part of a whole.

For example, if you have `1/2`, then you can say that you want one out of two. Fractions, in other words, tell you how much you have in comparison to the whole.
