The answer is 16. Just multiply 40 times .40 and you will get the answer. Another way is knowing multiples of ten. Anything times ten, just move the decimal point to the right which adds a zero. 40 * 10 is 400. To take the percentage, just move the decimal point to the left. 40.0 * 10% is 4.00. Now take that and multiply it 4 times to get 40% of 40 which equals 16. If you need to know 5 percent just divide 4.00 by 2 since 5 is half of ten.
I hope I did not confuse you but it is not difficult once you get the hang of it. This is also a great method to use if you are shopping and they are having a big 40% off sale.

40% = .4 because a percentage is multiplied by 100. so by dividing the 100 you get .4.
of means to multiply so .4 x 40 = 16.
