How To Work Out Percentages


Working out percentages at first, seems very complicated. However once you know how to do work them out, you will just think to yourself ‘why on earth could I not do that before?’

There is more than one way of working out percentages. We shall go through some of the ways on this post with the aid of examples.

One of the easiest ways to explain how to work out percentages is using the example of money. Consider the following question:

What is 10% of £5.00?

The easiest way to work this out is divide the value by 100, and then multiply by the percentage you need.

Step 1: Divide by 100

5 ÷ 100 = 0.05   So that leaves us with £0.05 or 5p

Step 2: Multiply by the percentage you need

0.05 x 10 = 0.5   So we now have £0.50 or 50p. And that’s the answer!

Here is another example:

What is 30% of 100 sweets?

Step 1: Divide by 100

100 ÷ 100 = 1

Step 2: Multiply by the percentage you need

1 x 30 = 30   And that’s the answer, 30 sweets!

It’s as easy as that!

Tips

To find 10%, just divide by 10

To find 50%, just half the figure

To find 1%, just divide by 100

How To Work Out Percentages of A Score or Exam Mark

Many of us want to know how to work out the percentage we have got when we achieve a particular score. The easiest way to do this is to first divide the score you have got by the maximum score possible. Then multiply the answer by 100.

For example I achieve 63 marks on a test. The maximum mark was 70. I divide 63 by 70 which gives me 0.9. I then times this by 100 to give me 90. So the answer is 90%. Simples.
