If you want to calculate the percentage of something, it’s simpler than you think. For ease, let’s use the number 200 as our example. As there are 100 percentage points to make a whole, it’s important to think of one per cent as a hundredth of the total amount. In order to calculate one per cent in 200, you would divide 200 by 100 in order to get two. Meanwhile, if you wanted 10 per cent, you would divide 200 by 10 in order to get 20. This is possible because 20 goes into 200 10 times.

Converting to percentages is far easier with decimals, where the first two decimal points are the tens and units of the percentage. For example, 0.69 of 200 is going to be 69 per cent, while 0.277 of 200 is going to be 27.7 per cent. See, it’s quite simple when you think about it!

Finally, let’s not forget that you might need to convert from fractions into percentages. In this example, we’re going to use three fifths. Now, there are five fifths to make one, and so we need to divide 100 percentage points by five in order to get 20, which is equal to one fifth. Now, in order to get 3/5, we need to multiply 20 by three, giving us a result of 60. And there you are: An easy conversion between fractions and percentages!
