Sorry, but you cannot calculate percentages at the pressing of a key. The calculator does not have a key for that. You will have to do it yourself.
To convert a decimal result to a percentage, multiply it by 100: MOVE the decimal mark two places to the right.
To convert a percentage into a decimal number, divide the number by 100: MOVE the decimal mark two places to the left.

SOURCE: my TI-83 plus calculator doesn't work

As battery gets drained, the screen contrast dims. But when you change batteries, some times the contrast is reset to some low value and the screen appears dead: it is so light that you do not see anything, and you think the calculator is malfunctioning. This is the most frequent reason users think the calculator refuses to turn ON. And I hope that is the case now.
To correct that, you must increase screen contrast: draken the screen a bit. To do so

  1. press [2nd] key and release it.
  2. Press the Up arrow and HOLD pressure.
  3. Keep pressing the arrow key until screen is dark enough.
If that solve your problem that is good, rate the post accordingly.. If that does not, do not get irate and berate the post. Post a comment here describing what you did and what message (if any) calculator returned, and I will give you further diagnostic steps.

That means that you know your calc crashed. This can be caused by taking out the batteries durring running time, happened just randomly. Well nothing to fear just press clear and it should go away but if it stays on that screen you have problems and is best to try some of these methods. Take out all the bateries and press and hold the on button for 30 seconds. Put the batteries back in and it should have reset. Warning you should archive everything incase this happens. To archive go to 2nd mem and hit enter to put a astrick next to the app (meaning archived)

Wha is a percentage number of another of another


Hmmm. Could you give more details? Are you wanting to find a percentage? If so, here's an example - 10% of 100 is 10.
Multiply 100 by .10 = 10.

So to find the percentage of a number, multiply the number in question by the decimal version of the percentage. 8% is .08, 15% is .15, etc.

I hope that helps!

What is the percentage of absentee owners, it 202 owners are non absentee and 67 are absentee owners


You would divide 67 by 269, and the correct percentage is 24.9%, rounded off to one decimal place. In essence, you divide the absentee number by the total number of owners, then multiply the answer by 100 to get the percentage.
Good luck, and hope this helps.

Increase percentage of 70 to 200


A percentage increase from a value a to a value b is defined as
Percent increase=(b-a)/a*100 percent.
In your case it is (200-70)/70=1.857. Multiply this number by 100 and append the percent symbol. Thus increase=185.7 percent or about 186 percent.
