Work it out. Don’t know it straight away? Look at the strategy.
- Write down the whole number: that is 100%.
- Divide by 2 for 50%, by 4 for 25% and by 10 for 10%.
- Build the requested percentage from these parts: 75% is 50% + 25%, 5% is half of 10%.
- For a discount, subtract that amount from the price.
30% of 80, 80 ÷ 10 = 8, 3 × 8 = 24
- 110% of 60 =1001060?
- 225% of 320 =10025320?
- 320% of 320 =10020320?
- 410% of 40 =1001040?
- 575% of 120 =100257512030?
- 610% of 250 =10010250?
- 720% of 60 =1002060?
- 810% of 70 =1001070?
- 950% of 370 =10050370?
- 1025% of 220 =10025220?
