how do i caculate the original value if i know what the result is and the percentage used to get to the result

Let the original number be x\nx*.012/100=498.9\nx=498.9*100/.012\n=49890/.012\n=4157500

hmm..well this might be an easy fix if you have a calculator\n\nsimply multiply the total by 0.1.  the answer will be 10 percent of the total.\n\nhope this helps\n\nexample: 132.00  x 0.1 = 13.20    which is 10%

Use a calculator.  It is 10845.25.

put that percent over 100\nex: 5%=5/100\npercent always means out of 100\nyou can also change that fration into a decimal by dividing the numerator by the denominator\nex: 5/100= 0.05\nand you can change the percent into a decimal by moving the understood decimal point to the left twice or dividing the decimal by 100. either way its the same thing\n5%=5.00%=0.05

you should be able to get the total through a "x" but otherwise, check the site

Take your calculator for any similar problem and divide, in this case, 60 by 75 and multiply by the decimal result by 100 and you will have a percentage. This works for all numbers. Take for example what is 19 of 20. Divide 19 by 20 and multiply time 100 and you will have 95%. This is how it is done.

An increase of 80% would be the same as multiplying by 180% (the original 100% plus the extra 80%)\n\nso you take 90 * 1.80 \n\nand you should have 162.

multiply amount owed(pay off) by % and add. subtract that amount from the original amount. if I am understanding you correctly.

What you do to solve all of these is you multiply by the percent. You can use a thing called DOOP. D=decimal, and P=percent OO= the two spaces to move. So to change from percent to decimal, use doop and move the decimal point back two spaces. Then you have a decimal, then times is by the number i will ONLY do the first five for you, and then you have to try the rest on your own. For the other types, make it into a fraction, then a decimal, then convert to percent!! (DOOP)\n1. 19\n2. 36%\n3. 92\n4. 88%\n5. 46.66666(repeated) %\n2.

simply multiply it with 0.4

Lets' say you start with 200 and you end with 260.  Your gain is 260-200=60.  Your percentage gain is 60/200=0.3=30%\n\nGain is (E-S)/S

% means divided by 100 so you just move the decimal 2 places to the left & drop the % sign\n7.8%=.078

Ideas for reverse percentage calculations \n\nThe value of a TV was increased by 10%. It has a new value of £440 after the 10% increase. What did it cost originally? \nTo solve this problem, we follow these logical steps. \nSTEP 1: Let us call the original value that we want to find 100% \nSTEP 2: After a 10% increase the new amount is therefore 110% \nSTEP 3: We know that this new 110% percent corresponds to a value of £440 \nSTEP 4: Because 110% = £440 \nDivide by 110 so 1% = £4 \nSTEP 5: The original cost was 100%. \n100% = 100 × 1% = 100 × £4 = £400 \n\nAnother way of doing it, using a calculator, is to do £440 ÷ 1.10 \nDividing by 1.10 reverses the 10% to give the original cost \n\nFor other type of examples refer the web source\nhttp://www.mathslearn.co.uk/notesperc2.html

To convert a decimal into a percent, move the decimal point two places to the right and add the % sign. If there are fewer than two places to the right of the decimal, add zeros at the end of the number after the decimal point. For example, 0.986 = 98.6% and 1.8 = 1.80 = 180%. \n\nTo convert a percent into a decimal, move the decimal point 2 places to the left and drop the percent sign. 36% becomes 0.36, and 145% becomes 1.45. If the number in front of the percent has fewer than two places in front of the decimal, add zeros to the left of the number, and then move the decimal place. For example, 5% = 05% = 0.05 and 1.78% = 01.78% = 0.0178.

First change the percent to a decimal. To do this, change the % sign to a decimal point and the move the decimal point two places to the left. Thus 12% =.12\n\nNow multipl this decimal by $250\n.12* $250 = $30

Just move the decimal place two spaces to the left ;)\n\n325. % = 3.25\n\n0.056 % = 0.00056

Simply multiply by 100.\n\nThe reason for this is simple.  We interpret percent as 1/100 so if we want to convert a fraction a/b to percent we have the following:\n\nc % = a/b ==> c * 1/100 = a/b ==> c = 100 * (a/b)\n\nYou may also want to convert a/b to decimal.  Although this is not essential.
