To find a percentage for example your score on a math test, you take your score on the test and divide it by the total marks of the test, and Multiply by 100. Ex. 50 marks on a test and you score a 45.
45 divided by 50 is 0.9, multiplying that by 100 gives you 90. Therefore your percentage was 90%
the new number divided by the old nuumber e.g If the new price is : £56 and the original price : £80 the percentage depreciation is: 56 / 80 = 0.7 ( the percentage decrease)
20% of them
Turn them into a fraction and then multiply it by 100
It is: 208/230 times 100 = 90.435% rounded to 3 decimal places
960 The easiest way to work out a percentage of something, is to convert the percentage into a decimal. 20% can also be written as 0.2 as a decimal. You can then multiply 4800 by 0.2. This works with any number as well. When the percentage is more difficult and you do not have a calculator, you can work out 10%, and then multiply that answer by 2 (to get 20%) Hope this helped :D
