I want to use the percentage key just for working out percentages and not for tax reasons.

e.g. 100 divided by 10% (to simplify matters)

Every time I try to do this I get a wierd answer.

Is the percentage key JUST for working out tax or can it be used as a simple percentage key?

HELP !!!!

best way to calculate percentages quickly is to multiply base number (100) by 1.xx (where xx is the percentage desired - here it would be 10 or just 1)

100*1.1=110

Works on every calculator every time.

100*1.1=110

On most Casio calculators you must type: '175 x 20 % -' (and '+' is for adding a percentage)

Your problem is that of percentage increase.

To calculate that, this is what you do:

Initial amount (Initial amount * percentage) = Percentage increase.

Let us call the initial amount, x.

Then our parameters are:

Initial amount = x

Percentage = 15/100

Final amount = 117300

So,

x (x * 15/100) = 117300

x (15x/100) = 117300

(x/1) (15x/100) = 117300

(100x 15x)/100 = 117300

115x/100 = 117300

cross multiplying

115x * 1 = 117300 * 100

115x = 11730000

dividing both sides by 115

115x/115 = 11730000/115

x = 102000.

So the original amount was $ 102000.

Hope that was helpful?

Have a wonderful day.

1÷1700 expressed as a decimal is 0.000588235, which is 5.882...×10^-4. [NB not 10^4]

To convert this to a percent, remember that "per cent" means "per 100" which also means "divide by 100". To keep the answer correct, if you are dividing by 100 you must also multiply by 100.

The get the answer in percent, you must therefore multiply the previous answer by 100 to get**0.00588235 percent**. (or 5.882...×10^-2 percent).

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.

FINALLY figured out how to change the tax rate! Press AC. Press and hold the Rate Set (%) button __UNTIL THE CURRENT TAX RATE IS DISPLAYED__. Enter the new rate you want (such as 7.5). Press the Rate Set (%) button again.

I have a Casino MS-80S and yea, the percentage works different. As example to take 100 and subtract 10%, this is what I do: 100 X 10% - and then I get the answer 90 after I press the minus key. To add the percentage instead, 100 X 10% + will give me an answer of 110, after I press the plus key.

I've been searching for the solution to this problem, as well. Apperently, there's no user's manual for this calculator. I'm going to call Casio on Monday to see if they can send me some sort of instructions. (800)962-2746 or (609)395-0154

good luck!!

Usually answered in minutes!

when doing acalculation such as 100 x 10% , i get 111.111etc...

i would like to just be able to use the percentage key properly.

Casio MS-8TV if i input 100 - 40% (actual key press) then the answer i get is 150. If i do 100 + 40% then i get 166.666. Its nothing to do with the tax button, and i have pressed the AC first. Just trying to do a simple % calculation.
