# Math Help - percent of number

1. ## percent of number

How would I work out 6% of 131?

2. 6% is simply 6/100

Multiply 6/100 by 131/1.

3. I got 0.0786
Is this right?

4. You're off by a couple of decimal points.

You should get 7.86.

5. How did you get that?
I'm awful at percentages!

6. Look:

6/100 * 131/1.

Multiply the top 131 * 6 = 786
Multiply the bottom 100 * 1 = 100

Now you have 786/100

How many times does 100 go into 786? 7

100 * 7 = 700

786 - 700 = 86.

Therefore 86 is what goes behind the decimal point.

9. When dividing by 10, 100, 1000 ... etc

You move the decimal place by the number of zeros.

786. -- In your case we need to move the decimal point to the left because were dividing (you move it to the right, when multiplying)

So when dividing by 100 we would move the decimal place over to the left 2 times.

7.86

If we divided by 10

78.6

by 1000

0.786

by 10,000

0.0786 -- If we multiply 0.0786 by 100,000 the decimal place moves to the right 5 times

7860. or just 7860

Hope this helps.

$6\% = \frac{6}{100} = 0.06$

$0.06 \times 131 = 7.86$
