Countdown to Exams - Day 32 - Percentages and percentage change
The focus for today is on Percentages and percentage change. You should be confident with common conversions as seen in the table as well as converting percentages into a fraction or decimal using the conversion flow chart. We then take a look at increasing/decreasing an amount by a percentage manually using two methods (Unitary method and Decimal method)
A calculator method is explored at the end and shows a quick way to increase and decrease an amount quickly using a multiplier factor. This method will help to work out original price problems. Finally we recap the formula used to calculate the percentage change between two values.
