You actually want to find out how much is 20% out of 150 and the calculation is really easy:

20/100 - this means 20 above 100 (a fraction)

20/100 * 150 = ?

You divide 20 by 100 which means 1/5 (1 over 5 - like a fraction)

When you divide 1 by 5 you get 0.2 .

Now you multiply 0.2 by 150.

0.2 * 150 = 30

That means that 20% of $150 is $30.

So if someone would say that from $150 they will keep 20% and give you the rest, that translate into the fact that that person is keeping $30 and give you $120.

I hope this answered your question.

Have a nice day :)

20% of $150 is $30. How you arrive at this number is quite simple, and while there are a couple of ways to do it, here is how I determine percentages. Take the second number (in this case the amount, $150) and times that by 0.20 (which is the decimal equal to 20%). This is how you determine the percentage.

...20% of 150 is 30. One easy way to do math like these is to simply find out the 10% and multiply it by 2 if your looking for 20% or by 3 if you want 30%.

So your answer is 30.

First, divide 20 by 100. 20/100.

You will get 0.2

Then, you multiply 150 and 0.2

The answer is 30.
