Ratio
If I have 3 apples you have 2 apples
In ratio, 3 : 2
I have 6 apples you have 4 apples
3 : 2
6 : 4
9 : 6
Given two numbers A and B in the the form of a ratio, A : B
If there are 2 of A then there would be 2 of B
(Which means 2 x A and 2 x B)
If there are 3 of A then there would be 3 of B
And so on
This is how you work out ratio
