Percentages needn’t be problematic. With our quick mathematrick you’ll be able to master them with ease.

First things first, you need to understand what percentages are.

The best way to start is by understanding the meaning behind.

Find 6 % of 300. Sound Difficult?

“Percent.” The first part is PER , as in PER = FOR EACH.

The second part of the word is CENT, which means 100 (as in century is one hundred years).

Therefore percent means per one hundred.

So, when someone asks what is 6 percent of a value, they are asking for the value of 6 per one hundred.

So 6% of 100 is 6 and 7.78% of 100 is 7.78.

So the question 6% of 300 could be thought of as:

6% of the first hundred is 6

6% of 2nd hundred is also 6

and, 6% of the 3rd hundred is also 6.

So 6+6+6 = 18.

If 6 % of 100 is 6, it follows that 6% of 50 is half of 6, or 3.

So to understand percentages, all you need to do is break down every number that’s asked into questions of 100.

If the number is less then 100, then move the decimal point accordingly.

EXAMPLES:

8%200 = ? 8 + 8 = 16.
8%250 = ? 8 + 8 + 4 = 20.
8% 25 = 2.0 (Moving the decimal back).
15%300 = 15+15+15 =45.
15%350 = 15+15+15+7.5 = 52.5

So there you have it, a simple guide to getting round percentages.

How Maths Teaching has Changed?

It’s funny how things have moved forward over the years. I’m showing my age slightly, but when I was growing up, I remember with some clarity (in black and white) how I was taught. There were blackboards, and dog eared text books – and pencils and pens. That’s a very...
