Percentages in depth: The easiest way to work out percentages without a calculator is this. 50% is halve of the number you want to work out a percentage of. Example 50% of 400 = 200. 25% of 400 is still easy. All you need to do is halve the answer you got for 50%. And halve of 200 = 100. 10% is still easy. All you have to do is divide the number (400) by 10. And that equals 40. 1% is still easy just divide 40 by 10 witch becomes 4. So If I needed to get 35% of 400 I would need to find out 25% witch equals 100, the answer of 10% witch is 40. All I need to do now is add 100 and 40 and that equals 140.
