Succeed with maths – Part 1

Week 5: Relationships among numbers

Introduction

This week, you will start your study of percentages. This will continue in Week 6, when you will use percentages in a variety of different everyday situations. Whether you are shopping around for the best deal, or reading an article online, understanding percentages can be useful in your everyday life. Percentages follow on naturally from fractions, because a percentage is just a specific kind of fraction, where the denominator (the number at the bottom of the fraction) is 100. So try and keep this in mind as you work your way through the activities here. You will notice that this week contains more activities for you to carry out than in some other weeks – this is to give you the chance to build your confidence with a concept that can at first seem quite challenging.

Maria Townsend
You may have heard the claim that we only ever use 10% of our brains. That means that if I could divide this model brain into a 100 equal parts I’d only ever be using 10 of them at any one time. That’s because each part represents 1%. This means 90% would be going to waste! Fortunately that’s just not true. I’ll show you other examples of percentages this week and how to use them.
