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.
