Re: Percentage button!!

The Casio MS-80TV requires you to input percentage calculations differently than other calculators. To calculate percentage change addition for this example, you must input "12000X20%+", for subtraction, you must input "12000x20%-".

Re: Percentage button!!

They call it hardware malfunction. try removing all batteries in it and wait for 30 seconds before reinserting the batteries. If the same problem still exist, the unit is permanently damaged.

small number divided by big number multiplied by 100 = %

example what % is 25 of 150

25 divided by 150 multi[plied by 100= 16.3 % approx or on your calculator-- small number divided by big number then % button

### How to convert percent to fraction

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

- Divide the percent by 100 to get decimal number.
- Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
- Calculate the factor (f) for making the decimal number an integer:
*f*= 10*to power d*

Example:

*f*= 10 power 2 = 100

- Multiply and divide the decimal number x by the factor f:
*x***f*/*f*=*y*/*f*

Example:

2.56 * 100 / 100 = 256 / 100

- Find the greatest common divisor (gcd) of the fraction.
Example:

gcd(256,100) = 4

- Reduce the fraction by dividing the numerator and denominator by the gcd value:
Example:

256 / 100 = (256/4) / (100/4) = 64/25

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

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!

The calculator is giving you exactly what you asked for, which is not the same thing as what you meant to ask for.

The SHIFT ( sequence converts a percentage to a decimal. 20% is 0.2, which added to 100 gives 100.2, as the calculator shows. If you want to increase 100 by 20%, you need to enter it as 1 0 0 + 1 0 0 * 2 0 SHIFT % = . See example 006 of the Appendix: http://www.fixya.com/support/p1400179-casio_fx83es_scientific_calculator/usermanual-4B2CDCC-pdf

Divide a number by another

8.23/12=0.69

percentage=0.69*100%=69%

Each calculator has its way of calculating percentages, percentage increase/decrease.

Here is a sample of the percentage calculations that the calculator can perform. You will not see among them the conversion from decimals to percentages.

To convert from decimals to percents move the decimal mark 2 places to the right and append the % sign.

To convert from percents to decimals, move the decimal mark 2 places to the left.

To convert from decimals to percents move the decimal mark 2 places to the right and append the % sign.

Divide .332 by .233, multiply by 100, then subtract 100.

Alternatively, since the increase in price was .099, divide .099 by .233 then multiply by 100.

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.

There is no percentage button. To turn your answer into a percentage, simply divide by 100. To find, for example, 64% of 200, type in .64*100.

Inputting a value and pressing SHIFT [%] converts the input value to a percent. For example:

2 SHIFT [%] = produces .02

To determine 20% of 150:

150 * 20 SHIFT [%] = produces 30

To calculate what percentage of 880 is 660:

660 / 880 SHIFT [%] = produces 75

To increase 2500 by 15%:

2500 + 2500*15 SHIFT [%] = or

2500 * (1+15 SHIFT [%] ) = produces 2875

To discount 3500 by 25%:

3500 - 3500 * SHIFT [%] = or

3500 * (1-15 SHIFT [%]) = produces 2625

To calculate the percentage change from 40 to 46:

(46 - 40) / 40 SHIFT [%] produces 15

2 SHIFT [%] = produces .02

To determine 20% of 150:

150 * 20 SHIFT [%] = produces 30

To calculate what percentage of 880 is 660:

660 / 880 SHIFT [%] = produces 75

To increase 2500 by 15%:

2500 + 2500*15 SHIFT [%] = or

2500 * (1+15 SHIFT [%] ) = produces 2875

To discount 3500 by 25%:

3500 - 3500 * SHIFT [%] = or

3500 * (1-15 SHIFT [%]) = produces 2625

To calculate the percentage change from 40 to 46:

(46 - 40) / 40 SHIFT [%] produces 15

this calculator is ****. it cant even perform a basic percentage calculation like a normal calculator.

The fact I have to come on here to look up solutions for a basic calculator says it all really...

Guest's Sept 27 entry works for me. But why should we have to do that? I blame Bill Gates.....

im not sure what you could maybe type in l/z that normally works

gives incorrect percentage
