Percentages and Financial Maths
Convert percentages to decimals and identify the original amount, change and final amount.
Key ideas
- percentage of quantity
- increase/decrease
- discount
- profit/loss
- simple financial problems
Formula / rule: new amount = original × (1 ± percentage as decimal).
Worked example: 15% increase uses multiplier 1.15.
Common trap: A 20% increase followed by 20% decrease does not return to the original.
Key words
percentage — parts per hundred
discount — price reduction
markup — increase added to cost
profit — selling price minus cost
loss — cost minus selling price
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
