How do you change 15 percent into a decimal?

Answer 1

To change a percentage into a decimal, just pretend there is a decimal at the end of the percentage and move it two places to the left.

So we have 15.

Step 1:

Put a decimal at the end of the number

15.

Step 2:

Move that decimal two places to the left, or two numbers to the left.

.15

Now, .15 is your answer. With any two digit percentage, you can simply stick a decimal infront of the percentage, and that's your answer.

Like...

22%=.22

95%=.95

69%=.69

Now, let's try a one number percentage.

Say, we have 5%. We need 5% in decimal form.

Step one:

Put a decimal after the number

5.

Step two:

Move that decimal over two places to the left.

.05

If there is no number before the first number to move the decimal before, simply put a zero there.

For any one digit percentage, you can simply put a decimal and a zero before the number!

Like..

2%=.02

3%=.03

4%=.04
