PER CENT means ‘out of every 100’. For example if you say 55 per cent of the school children are girls, it means that out of every 100 school children 55 are girls. The rule is that to work out a percentage you first work out the fraction and then you multiply that by 100. In this example the fraction that are girls is 55/100. The percentage that are girls is 55/100 x 100 = 55 per cent. So if you want to change percent back into a fraction you divide by 100. 55 percent divided by 100 is 55/100 . Another example: I have 500 balls. 200 are black. The rest are red. What is the percentage of red balls. Answer: The number of red balls is 500 – 200 = 300. The fraction of red balls is 300/500 = 3/5. The percentage of red balls is 3/5 x 100 = 300/5. 300/5 = 60. So 60 percent of the balls are red. A short way of writing this is 60%.
