How do i calculate one constant dollar figure by 8 different percentages without re-entering the dollar figure each time?

To find the percentage of a number: Let's say you want to find 20% of 150.

• Enter the number you want to find the percentage of (150 in this example).
• Press the multiplication key (*).
• Enter the percentage value (20 in this example).
• Press the percentage key (%).

The calculator will display the result, which in this case is 30 (20% of 150 is 30

To use the power, you use the y to the x key, above the EXP key. To enter 2 to the power of 4, you enter 2 hit the y to the x key and enter 4 and hit enter.

To use percent function, you enter the percent key after the number. To calculate Interest, where Interest = Principal x Interest x Time. For example, if the principal is $1,000, the interest rate is 8%, and time/term is 4 years, we would enter 1000 x 8 Percent x 4. When the8 is entered followed by the percent key, it should turn into 0.08.

Good luck,

Multiply the percentage by $1600.00 then divide by 100.

For example, to calculate 20%, multiply 20 by $1600.00 to get $32000 then divide by 100 to get $320.00

100*4117484/163715657 gives me about 2.5%. Since you didn't specify the calculator your're using, I can't give you the exact keystroke sequence, but on a typical algebraic calculator it would be something like 1 0 0 * 4 1 1 7 4 8 4 / 1 6 3 7 1 5 6 5 7 =

On an RPN or RPL calculator, it would be
1 0 0 ENTER 4 1 1 7 4 8 4 * 1 6 3 7 1 5 6 5 7 /

Enter the number, press =, then press the S--D key (located above the red DEL key).

For example, to see what 25% is, type . 2 5 = S--D

Note: if you're in the LineIO mode you will see something like 1 _ 4. If you want to see it as a "real" fraction, press SHIFT MODE 1 to switch to the MathIO mode.

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 %
Answer: 85
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 % =
Answer: 90.35 or $90.35
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

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.

You must enter 100+10%100 or 100+10%(100). This will give you the correct answer of 110.

Hi nastyguy3000;

To calculate a percentage in excel you simply take
amount/total = percentage in your cell

Example A B Purchase price Sales tax (in decimal form) 800 0.089 Formula Description (Result) =A2*B2 Multiplies 800 by 0.089 to find the amount of sales tax to pay ($71.20)

Have Fun

Don't forget to leave a rating.

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.
