Here's A Genius Math Hack So You'll Never Struggle With Percentages Again

Few people are able to figure out percentages without needing a minute to do a bunch of math in their head and even then, many still come up with the wrong answer. However, it turns out that there is a math hack that can help. A Twitter user shared it, calling it a "fascinating little life hack for doing percentages." He pointed out that x% of y is the same as y% of x. While that might look complex as an equation, and technically still has you doing percentages to figure out percentages, it actually can be incredibly helpful.

So instead of finding 4% of 75, you can reverse it and find 75% of 4, which is much easier. If you didn't know off the top of your head that that is 3, you can just multiply 75 by 4, which equals 300, and then divide by 100.

This means instead of finding out difficult percentages like 18% of 50, you can just do 50% of 18, which of course is 9.

 

The responses to the tweet show how life-changing the hack is for some people:

 
 
 
 
 
 

Sure it might not help when you are finding out 43% of 57 or other tough numbers like that, but it will definitely give you a step up in easier cases!
