How you change percent to a decimal?

Answer 1

When changing a percent to a decimal, you move the decimal point at the end of your percent back two spots. When changing a decimal to a percent, you move the decimal point on your decimal over two places to receive your percent. When a decimal is repeating, you still treat it like a regular decimal. You move the decimal point over two places, then on the first repeating number, put a bar over it. For example: .033333333333… changes to this percent: 3.3%. For a terminating decimal, you could round up to the one's place, stop the decimal at some point, or continue the decimal all the way through. For example, if you have the decimal .768021, you could choose to use 77% or 76.8021%. You could even choose to use 76.8%. When you have a decimal with a whole number in it, such as 9.346, that would conclude in a percent greater than 100%. That decimal would actually equal 934.6%! When you have a percent greater than 100, that means you have more than one whole. When you change a percent to a decimal, it is basically the same concept. For example, if you have 67%, you would just move the decimal point back two places. The decimal would be .67. If you have a more complicated percent, such as 67.83859%, you still move the decimal back two places and your answer would be .6783859.

Answer 2

Remove the percent sign, then divide by 100. Or move the decimal point two places to the left. 30%=.30, 57%=.57, 100%=1

A percent--let us take 99% for an example--is merely 99/100, the % symbolizing the number divided by 100. 99% means .99; 1% means .01 because it is 1/100; .7% means .7/100, which we can say is 7/1000, which is .007.
