3. 6. difference between percentages and percentage points we should clearly distinguish between 'percentages' and 'percentage points', to know well how to apply each of them. as we have seen along the previous exercises, a percentage is a proportion that takes number "100" as a reference. for example, if a question says that the population of france is 11% of the population of the eu, and the population of the eu is (in round figures) 500 million people, then we can calculate the population of france (the unknown "x" in this case), using the "rule of three" that we all know from basic maths and we are going to review here. according to what we have said, "11%" indicates the proportion "11 to 100", so our rule of three in this case will be: 11 is related to 100 as x is related to 500 and we can solve this by cross multiplication: 11 100 500 this way: 11 * 500 = x * 100 and clearing: x = 11 * 500 / 100 x = 55 so our answer to this question would be that the population of france is 55 million people.
