Finding Percentages Without a Calculator
Finding percentages becomes much easier when you use the building block method. Start with 10% (just divide by 10), then build up to whatever percentage you need.
For 15% of £65, you'd find 10% first by dividing £65 by 10, giving you £6.50. Then get 5% by halving the 10% amount . Add them together: £6.50 + £3.25 = £9.75.
For trickier percentages like 32%, break it down into 30% + 2%. Find 10% of £41 (£4.10), multiply by 3 for 30% (£12.30). Then find 1% by dividing by 100 (£0.41), multiply by 2 for 2% (£0.82). Finally, add: £12.30 + £0.82 = £13.12.
Quick Tip: Remember that 10% = divide by 10, 5% = half of 10%, and 1% = divide by 100. These are your building blocks for any percentage!
