Percentages seem to confuse a lot of people but they really shouldn't. A percentage is simply a fraction. 40% is written as .40 or 4/10. So let's say your given number is 20. To add 40% to 20 you multiply 20 by 1.4 and the answer is 28. The reason you multiply by 1 is you are ADDING 40% so you want the original number you started with. 20 times 1 equals 20. So we have our original number in our answer. The .4 comes from 40%. 20 times .4 equals 8. So 20 plus 8 equal 28.
There are two answers to that. If you get 80% of 40 and add it on, you get 72. If you get 80% as a value and add it to 40, you get 40.8
You cannot add to 90 per cent to make a smaller percentage.
