We are all sure that calculating percentages is very difficult, and if we do not always use a calculator for this, then we certainly always use the good old school proportion. If you want to learn how to quickly calculate percentages in your head, this video is for you.
It doesn't matter if you're counting out a tip to the waiter or you just need to do some math quickly, percent is something that can confuse even a physics student.
Here's a video to show you how to quickly calculate percentages in your head.
We all remember from school how to find 10% and 50% of a number. Knowing this, you can find other percentages using simple manipulations. For example:
- To find 5%, find 10% and divide by two.
- To find 15%, find 10% and then add 5%.
- To find 20%, find 10% and multiply by two.
- To find 25%, find 50% and divide by two.
- To find 60%, find 50% and add 10%.
- To find 75%, find 50%, then add 25%, and so on.
As we can see, knowing the "simple" interest, you can find almost any percentage. So feel free to put the calculator aside.
