Week 6: Percentage calculations and ratios
This week, you will continue your study of percentages. After a refresh of some of last week’s ideas, you will turn your attention to carrying out calculations with percentages. This will help you to feel confident in using these in different situations, such as working out a reduction in price. Finally, you’ll spend a little time learning about ratios. Again, this session contains more activities for you to carry out than in some other weeks to provide opportunities to practise your skills and grow in confidence.
