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%-".

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

If you want to find 25% of 500

ENTER....

500 X 25 [2ndF] % will display 125.

If you want to know what % a number is of another number like for instance...

What percentage is 120 of 400?

ENTER...

120 [DIV] 400 [2ndF] % will display 30.

If you want to increase a number by some percentage like

Increase 500 by 25%

ENTER...

500 + 25 [2ndF] % will display 625.

If you want to decrease a number by a percentage like

Decrease 400 by 30%

ENTER...

400 - 30 [2ndF] % will Display 280.

NOTE [2ndF] is the 2ndF button. Do not enter the brackets [ and ].

NOTE [DIV] is the divide button. The text editor would not let me enter the divide symbol

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.

Percentages are calculated by using the following equation:

amount/total = percentage

Where percentage is in decimal format.

What do you want to do?

Calculate the amount if you know the total and percentage
For example, if you purchase a computer for $800 and there is an 8.9% sales
tax, how much do you have to pay for the sales tax? In this example, you want to
find 8.9% of 800.

Example
The example may be easier to understand if you copy it to a blank
worksheet.

- Create a blank workbook or worksheet.
- Select the example in the Help topic.
**Note**Do not select the row or column headers.

Selecting an example from Help - Press CTRL+C.
- In the worksheet, select cell A1, and press CTRL+V.
- To switch between viewing the results and viewing the formulas that return
the results, press CTRL+` (grave accent), or on the
**Formulas**tab, in the**Formula Auditing**group, click the**Show Formulas**button.

Calculate the percentage if you know the total and amount For example, if you score 42 points correctly out of 50, what is the percentage of correct answers?

To calculate using fractions you should use the [A B/C] button located on the 3rd row 2nd column of the keypad. For example, if you want to calculate 3 1/2 + 3/4, you should input 3 [A B/C] 1 [A B/C] 2 [A B/C] [+] 3 [A B/C] 4 [A B/C] [ENTER]. You should get an answer of 4 1/4. To convert that into percentages or decimals press the [2nd] button first then the [FD] button which is the [PRB] button. For example to make 4 1/4 to appear as 4.25 you press [2nd] then [PRB] ([FD]) then [ENTER]. If you want it into a percentage, multiple the decimal value by 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
