Tips and Tips on Percentage Calculation

A lot of percent problems turn out to be easy to calculate when you give them a little thought. Here’s a trick (Source: Basic Math for Dummies) that makes certain tough-looking percent problems so easy that you can do them in your head. Simply move the percent sign from one number to the other and flip the order of the numbers.

Suppose someone wants you to figure out the following:

88% of 50

Finding 88% of anything isn’t an activity that anybody looks forward to. But an easy way of solving the problem is to switch it around:

88% of 50 = 50% of 88

This move is perfectly valid, and it makes the problem a lot easier. 50% of 88 is simply half of 88:

88% of 50 = 50% of 88 = 44

As another example, suppose you want to find

7% of 200

Again, finding 7% is tricky, but finding 200% is simple, so switch the problem around:

7% of 200 = 200% of 7

To find 200% of any number, you just multiply that number by 2:

7% of 200 = 200% of 7 = 2 ⋅ 7 = 14
