What is a ratio?
A ratio is simply a way of comparing two or more quantities.
What does a ratio look like?
A ratio is just two numbers written with a colon between them. For example 3:5 2:7 etc
Does the order matter?
Yes, absolutely. 3:1 is not the same as 1:3
Example 1: I have 4 red balls and 6 blue balls. Write a ratio for the amount of red balls to blue balls.
We have to look at the question here, it asks for red to blue balls. This can be written as 4 : 6.
While this can be cancelled down, don't worry about that at this point, we will focus on that in another lesson.
