### Staples scientific calculator BD-107i

To find percentages on this calculator, or any calculator, you divide one number by the other, and multiply the result by 100.

For example, for 2 out of 5, we type in 2, hit the divide button, type in 5 and hit the equals sign and we will get 0.4. To make this into percentage, we then multiply the answer by 100 to get 40%.

Good luck,

Paul

### How to convert percent to fraction

1. Divide the percent by 100 to get decimal number.
2. 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.
3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
Example:
f = 10 power 2 = 100
4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
Example:
2.56 * 100 / 100 = 256 / 100
5. Find the greatest common divisor (gcd) of the fraction. Example:
gcd(256,100) = 4
6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
256 / 100 = (256/4) / (100/4) = 64/25
Example One percent is equal to one hundredth:
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

### I can't figure out how to use percent sign?

If I want 2/5 as a percentage (which is 40%), I would press
[2] [ /] [5] [%]
Instead of equal sign, I'll press % sign, which will give the answer as a percentage.
Of course this is a simple calculation. If you want advanced calculations let us know.

### How to calcolate %

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

### Acer,Aspire 5720-4663 Math calculator: How does one use the percentage function?

Hi. Try this steps on using your math calculator for the percentage function.

Hope This Helps

Step 1. Note that not all calculators behave the same way as far as the percentage key is concerned. Thus, test the examples in this article on your calculator. If your calculator does not have the percent key or does not behave in the way described here, don't despair - you can still use it to calculate percentages, it's just that you will have to press a few more buttons.
Step 2. Let's calculate a tip on your restaurant bill. Suppose your bill happens to be \$64.35 and you would like to leave 15% tip.
Type the following into your calculator: 64.35 * 15 %
Answer: 9.6525 or \$9.65 after rounding.
Most simple calculators will give an answer right here without having to press the = sign. If yours does not, press = and see if you get the right answer.
Alternatively, you can calculate this percentage by typing in
64.35 * 15 / 100 or 64.35 * 0.15
Thus, you may have observed that all that the percent key did here was division by a hundred.
Step 3. Let's calculate a grade percentage - say you got 34 out of a maximum of 40 points.
To figure out your grade percentage type in: 34 / 40 %
Alternatively, without the percent key: 34 / 40 * 100
Step 4. Let's calculate a sale price on those shoes that originally cost \$139, but are now discounted by 35%.
On your calculator type in: 139 - 35 % =
This calculation is amazingly easy with the percent key! Alternatively, you would first have to calculate what the 35% of the \$139 is and then subtract it from 139:
139 * 35 / 100 = 48.65
139 - 48.65 = 90.35
