A ratio is a comparison of two quantities, which are usually expressed as a fraction of the other. The most common examples involve two quantities, but actually, in reality, any number of quantities can be involved!

Okays.

Since we have learnt about ratio in our primary school days, i will just refresh the memory we have of ratio, dear people.

Let's begin with an example question:

To make a jug of orange juice, mix the juice and water in the ratio of 1 : 4. (PS. This means that you mix one part of juice to four parts of water).

Oh yes....
Important thing to note.....

The order of the numbers is important;

1 : 4 is NOT equal to 4 : 1

Yup!

Signing off,
