Percentages refer to fractions of a whole; that is, whatever you're looking at, the percentage is how much of the whole thing you have. For instance, "50%" means " 1/2 "; "25%" means " 1/4 "; "40%" means " 2/5 "; et cetera.\n\nOften you will need to figure out what percentage of something another thing is. For instance, if a class has 26 students, and 14 are female, what percentage of the students are female?  It is 14 out of 26, or 14/26 = 0.538461538462..., or about 54%. (For more information on percent word problems, look at the Percent of lesson.)\n\n"Percent" is actually "per cent", meaning "out of a hundred". (I think it's Latin.) You can use this fact, along with the fact that fractions mean division, to convert between fractions, percents, and decimals.\n\nPercent to Decimal\n\nPercent-to-decimal conversions are easy; you mostly just move the decimal point two places. The way I keep it straight is to remember that 50%, or one-half, of a dollar is $0.50. In other words, you have to move the decimal point two places to the left when you convert from a percent (50%) to a decimal (0.50). Some more examples are:\n\n      27% = 0.27\n      104% = 1.04\n      0.5% = 0.005\n\nPercent to Fraction\n\nPercent-to-fraction conversions aren't too bad. This is where you use the fact that "percent" means "out of a hundred". Convert the percent to a decimal, and then to a fraction.

Simple:  $250,000 X 3 X 4.3 divided by 12 X 100.\n\nThe answer above this one can't be right:  it's more than 400%.

13/32 = .40625 so about 40% or 40.625% if you want to be exact.

The first thing to remember about percentages is that they represent a fraction who's denominator (bottom term) is 100 - for example, 40% is the same as 40/100 = 4/10 = 2/5.  And the second is something I learned in math class about 40 years ago about percentage word problems - "percent" over "100" equals "is" over "of".  Burn that into your brain.  How do you use it? In your problem, "40" is the "percent", and "85" is the "of" (because it comes right after the "of"). So using the rule, your problem is:\n\n40/100 = is/85\n\nThere's no "is" in you problem, therefore it must be the answer we have to solve for, right?  So now you cross-multiply:\n\n40*85 = 3400, and 3400/100 = 34, which is the answer.\n\nWhat if your problem asked, "What percent of 85 is 34?" \n\n34 is the "is" since it comes right after the word "is" in the problem, and 85 is still the "of" since it comes right after the "of", and since the problem asks "What percent...", percent is what we have to solve for.  So using the rule, the problem sets up to:\n\npercent/100 = 34/85 \n\nNow cross multiply again:\n 34*100 = 3400, and 3400/85 = 40, so 40 is the "percent", and therefore the answer!  One more example: "34 is 40% of what?"  This time, it looks like "of" is what we have to find, so the problem sets up to:\n\n40/100 = 34/"of"\n\nCross multiply again:\n\n100*34 = 3400, and 3400/40 = 85\n\nSee how easy percentage word problems are?  Practice 30 problems like this, and don't forget that "percent over 100 equals "is" over "of", and remember how to cross-multiply.\n\nGaryH

50% is always half!\n\nI don't agree with "when the whole isn't 100%" theory, because isn't that the definition of whole?! Whole is 100%. Whole is ALWAYS 100%! Half of the whole is 50%! No exceptions!

We need to add x liters of 10% solution to 40 liters of 50% to get (40 + x) liters of 40%.\n\nx*(10/100) + 40*(50/100) = (40 + x) * (40/100)\nTurn the fractions into decimals:\n.10x + 40(.5) = .40(40 + x)\nMultiply through the parenthesis:\n.10x + 20 = 16 + .40x\nSubtract 16 from each side:\n.10x + 4 = .40x\nSubtract .10x from each side:\n4 = .30x\nDivide each side by .30:\n4/.30 = x\nYou can solve right from here, but I would multiply the top and bottom by 10 to get a cleaner fraction:\n40/3 = x\nx = 13 1/3 liters (or 13.33 if you need a decimal answer)\n\n\nTo check this out, 13 1/3 liters of 10% solution added to the 40 liters of 50% solution should make 53 1/3 liters of 40% solution.\n13 1/3 * 10/100 = 4 / 3 = 1 1/3\n40 * 50/100 = 20\nSo you have a total of 21 1/3 liters of alcohol\n\n53 1/3 * 40/100 = 64/3 = 21 1/3\n\nThis can be done using decimals also, but I find a fraction of 1/3 to be much cleaner than .3333333333
