How do you convert decimals to fractions? and fractions to decimals? It has been too many years, I forgot

to change a decimal into a fraction take the decimal lets say .56 and put to over 1 with as many zeros that there is in the decimal so it becomes 56/100 then reduce to its simplest terms....56/100=14/25  and viola!\n\nto turn it into a decimal just divid it so it would be 14 divided by 25 ...and you get .56! \n\nhope this helps :)

If decimals are allowed, then (73+7)*.3 is a nice solution :)\n\nIf not, then the only solution I could find is (3+(3/7))*7\n\nEDIT : As for the initial question, absolutely! Math is my favorite subject, even in college. I won several contests in high-school, and love any sort of math puzzles. If you know of any more, please e-mail me :)\n\nSubmarinerdave : Heh. That's what I thought of as well, my sister has a 24 contest at her school two years ago :) A similar but more challenging game is the 2006 math game, where you try to make numbers from 1 to 100 using the digits 2,0,0, and 6. Link below.

Going from percent to fraction is easy.  Percent literally means "per 100" so just divide your percent by 100 to get a fraction.  For example, 16% = 16/100.  You can then simplify if you want, to get 16/100= 4/25.\n\n~ ~ ~ ~ \n\n66 2/3% = 0.66666.... or 0.6 (with a dash on top of the 6).  The fraction is 2/3.\n\nTo go from a repeating decimal to a fraction, it's a little tricky. Here's how you do it:  Notice how many numbers are in the repeating pattern -- in this case it's only the 6, so we have 1 repeating number.  Use this "1" to tell you that you need to multiply your decimal by 10^1 to solve.  (If our repeating decimal was 0.181818... that would be two repeating numbers and we'd need to use 10^2 to solve.)  Anyhoo, we have 1 repeating number, so take your decimal, call it x and take 10^1 times x minus x to solve:\n\n10x - x = 6.666... - 0.6666\n9x = 6\nx = 6/9 = 2/3\n\nAnd that's how you go from repeating decimals to a fraction!\n\n~ ~ ~ ~ \n\n18/15 = 120% = 1.20\n\n~ ♥ ~

It's not, because not all fractions convert easily to decimals.  Example: change 4/13 to a percent.\n\nMuch faster to say 4/13 = p/100, cross multiply to get 13p = 400,\n\ndivide to get 400/13 or 30 10/13 %

You can find the answer by turning the fraction into a decimal. Divide the denominator into the numerator. \n\nSo, for example, divide 3 into 1. This will give you the fraction expressed as a decimal. Then compare it to .35.\n\nDo the same thing with the second one.

the first three questions are answered as follows\n~ = means repeating decimal\n#1     $75 - (75 x .333~) = $50\n#2     $150 - (150 x .5) = $75\n#3     $750 x .1 = $75\n\nthe easiest way to the the additional problems you have add is as follows\n\n#1    80 x .2 = 16\n#2    50 x .5 = 25\n#3    40 x .1 = 4\n#4    68 x .25 = 17

1. 0.4 = 4/10 = 2/5\n\nThis is because 0.4 is basically 4 out of ten. If there is 1 number behind the decimal, it is out of ten. Two numbers, then it is out of one hundred. Three, one thousand. And so on and so forth. 4/10 simplifies to 2/5.\n\n2. 0.04 = 4/100 = 1/25\n\nDitto.\n\n3. 0.84 = 84/100 = 44/50 = 22/25\n\nHope that works for ya. I'm sure it's right. =]\n\nRayy

Divide top number of the fraction by the bottom number \n(1/4 = divide 1 by 4 = 0.25) That is fraction to decimal. \nTo get percentage just multiply by 100. \nSo the 0.25 becomes 25, or 25%\n\n: - )

It's so that the person you are talking to knows what you are talking about.\n\nWhat would the alternative be? "Twelve and seven hundred and eighty-nine thousandths?" That's a bit cumbersome.\n\nThe decimal point *creates* a division between the numbers, so we need to replicate that division by saying "point." It just makes sense.

Those are the right numbers. As you suspected they have too many decimal places, however. To have them correct to 6 decimal places, look at the 7th decimal place. If this is 5 or more, round the 6th decimal up one, otherwise leave it the same and just drop all the numbers after it.\n\nSo for a) the answer would be 1.499975 and for b) it would be 1.499997.

This is actually elementary math. If you remember the order of operation, it helps. \n\nStep 1: Do the part of the problem in the parenthesis.\n  Example: (4/3)= 1.3333333333 (you get where this is going)\n\nStep 2: Take that answer and multiply it by the named multiplier.\n  Example: 1.33333 * 12= 16\n\nStep 3: Take the result of that transaction and devide it by the named devisor. For this method don't use the fraction way, and don't use a calculator. Do a basic devision problem like you were taught in the 3rd grade using the "bracket."\n  Example: 16/13 = 1  (13 goes into 16 1 time)\n\nStep 4: Subtract the 13 from the 16 and it will give you your remainder.\n  Example: 16/13 = 1   16-13= 3\n\nThe answer when written correctly isn't with a decimal but would look like this- 1 R3.\n\nAlso for a little note for this- Order of operation:\nP (parenthesis)\nE (exponents)\nM (multiply)\nD (devide)\nA (addition)\nS (subtraction)\n\nHope this helps!

The previous responders have given you the answer for a terminating decimal. (That means a decimal that has a certain number of decimal places, and then all the rest of it is zeroes. For example, .9187 is a terminating decimal, which could be extended with zeroes as .918700000000000000000....)\n\nBut you may be asking about repeating decimals. These are more interesting. Here's how you convert them to fractions.\n\nIf there is only a single digit that repeats (such as .3333333333....), you take that digit and put it over 9:\n.3333333333.... = 3/9 = 1/3. (Note that you should put the fraction in lowest terms (1/3, in this case) after you put the digit over 9.)\n\nIf there are 2 digits that repeat, you put them over 99. For example, .636363636363636363.... = 63/99 = 7/11.\n\nAnd if there are lots of digits that repeat, you put them over the same number of 9's. For example, .71237123712371237123.... = 7123/9999.\n\nThere are other tricks, such as a decimal that doesn't repeat until after the first few decimal places (e.g., .7633333...), but the above rules should handle most of the situations you encounter.

Devided??? It is Divided...\n\nA half of something is 50%. A half in decimal terms is 0.5. \n\n1/4 of something is something that can be divided four times into 1. That would have to be 0.25 which is one quarter. If you want three quarters you times the 0.25 by 3 which will make 0.75\n\nThat is if you are asking as question 1 and question 2. \nIf you were not then it's simply 1.5 or 2.75.\n\nHope this helps,\nGraham

A decimal is just a fraction over 100.  So 75% is the same as 75/100.  Then to reduce it to its simplest terms, you find the number (in this case 25) by which both numbers can be divided and have whole numbers as a result.  75 divided by 25 is 3; 100 divided by 25 is 4.  So my example is equal to 3/4.  Once I get that far, there are no further factors (even dividing numbers) that 3 and 4 have in common, so I have reduced the fraction to its lowest terms.  75% is therefore equal to 3/4.\n\nIf the decimal value includes further decimals (as in 37.5%) you start with enough extra zeros to cancel out the decimal.  So, in this example 375/1000.  Then reduce.  Go ahead; it won't bite you.\n\nOK.  You don't know what numbers to use.  Start with 5, because it will work:  75/200.  Well, now I see I can use 25 again:  3/8.  And we've once more gone as far as we can.

count the number of decimal places\nin your example, its 7\nyour example becomes the numerator (remove the decimal point)\nand 1+ seven 0s be the denominator\nso its\n1285714/10000000

change mixed fractions to proper fractions and then divide,\nwhats so hard?
