Not knowing how to get the percentage on a figure from a calculator

Divide 195 by 0.65 to get 300.

Divide 84,180.26 by 1,580,890.55 then multiply by 100 to get about 5.3%.

The percentage of what? The interest rate? The percentage of the principal to the amount? The percentage growth?

Multiply the gross figure by 33 then divide by 100. Some calculators have a % key to simplify percentage calculations but since you didn't specify a particular make and model I can't say whether yours does or not.

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.

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.

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

Hi the simplest way to calculate the percentage is
13/16*100 = answer (81.25 % will be your answer)
