How would I work out 6% of 131?

- Mar 10th 2008, 07:47 PMintegrator10101
6% is simply 6/100

Multiply 6/100 by 131/1.

You get 786/100. Now, reduce and you have your answer. - Mar 10th 2008, 07:51 PMmathsnoob
I got 0.0786

Is this right? - Mar 10th 2008, 08:01 PMintegrator10101
You're off by a couple of decimal points.

You should get 7.86. - Mar 10th 2008, 08:02 PMmathsnoob
How did you get that?

I'm awful at percentages! - Mar 10th 2008, 08:12 PMintegrator10101
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. - Mar 26th 2008, 09:29 AMnikconsult

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. - Apr 1st 2008, 02:20 AMSimplicity

Hello,

Is it .30% or 30% ?

One will be 30/10000, the other will be 30/100

X% of Y is always X*Y/100

This means here that it's 68*30%=68*30/100=20.40$
