Ths is another video in this introductionary chapter for the Year 11 General Maths course. Having looked at a lot of the basics of Mathematics which will be used throughout the rest of the course, I am now going to spend a short amount of time looking at Ratio and Proportion. What is a ratio? What does it mean by proportion? How do I express a ratio? These are all questions which are answered. There are a number of worked examples which I use to explain the theory in a clear and easy to understand way.
