# percentages

I'm struggling with how I work out 21% of 52. I was never any good at percentages.

52 x 21/100 = 10.92

Break it down..First, divide by 10 to get value of 10%So 52 divided by 10 equals 5.2 (the numbers shift to the right by one place in terms of place value).Then work out 1%..So 5.2 divided by 10 equals 0.52Then multiply your answer for 10% by 2 to get 20%5.2 times by 2 equals 10.Then, add your answer for 20% to your answer for 1%So 10.4 plus 0.52 equals 10.92This is the way I would teach it so that you understand what is going on - especially if you did not have a calculator. The other method below is great to put straight into your calc - as long as you know which numbers to put in!

Hi KevinTo work out a percentage of a number. You divide what you have by 100 and then multiply it by the percentage you need. So for this example we have 52 divided by 100 and then multiplied by 21The answer will be 10.92

Hey to solve your problem you can do the following methods:21% of 52Method 10.21*52 = 10.92Method 210% of 52 = 5.210% of 52 = 5.21% of 52 = 0.52Therefore adding these together gives = 21% of 52 = 10.92Method 3(21/100)*52 = 10.92Hope that helps!
