how do i convert these numbers to fractions

Take each one and put in over 1000 and then reduce.\nYou use 1000 because there are 3 decimal places.

Hi. 0.754 x 1.0 would be obvious.  0.754 x .1 would involve moving the decimal point one place to the left.  0.754 x 0.8 would involve solving for the last value and adding 8 times.

fractions into decimals\n\neasy way is 7/100 \ndivide 7 by 100 and you will get 0.07\n\ndivde mix fractions like 2 5/8\nchange into improper fraction 21/8\nthen divde 21 by 8 and you will get 2.625

i=r/k  (Divide by 100 to change from percent to decimal.)\nn=kt

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~ ♥ ~

original problem: 1/3- 1/2y < 12\n                            1/3-1/3- 1/2y <12- 1/3\n                               -1/2y < 11& 2/3\n                              divide both sides by -1/2 to get:\n                                y> 23 & 1/3

First change them to improper fractions to do this multiply the whole number by the denominator so in 3 and 7/8 you would take 3 times 8, once you got that you would add it to the numerator so\n\n3x8=24\n7+24=31\n\nso you have 31/8 for the first fraction\n\nrepeat this step for the second\n2x10=20\n20+9=29\n\nthe second is 29/10\n\nNow you must fine the lowest common denominator for both fractions, which means find a number both 8 and 10 divide into evenly. Both go into 40 evenly, so you want the denominator to be 40 on both fractions, to do this multiply the top and bottom of each so that the denominator is 40 so for the first fraction, 31/8 you would multiply both the top and bottom by 5.\n\n(31/8)x5=155/40\nand the second fraction\n(29/10)x4=116/40\n\nnow you can subtract them\n\n(155/40)-(116/40)=39/40

I'll just tell you enough and then you do the rest.\n\nEach of them involves a number which is a mixture of whole number and fraction.  First step is to exress it as an improper fraction, e.g.\n2) 3 5/8 = 24/8 + 5/8\n             = 29/8  \n(simple rule is \n(denominator*whole number + numerator)/denominator)\nLikewise 2 1/2 = 5/2\n\nI expect you can do\n(1/2)*(29/8)*(5/2)\n\n3) Same idea for 4 1/5, only extra thing to know is that to divide by 14 you multiply by 1/14.\n\nCheers

Divide the decimal number by 16.   Treat the division as an integer division.   \nWrite down the remainder (in hexadecimal). \nDivide the result again by 16.  Treat the division as an integer division.   \nRepeat step 2 and 3 until result is 0. \nThe hex value is the digit sequence of the remainders from the last to first. \ncheck here: http://www.permadi.com/tutorial/numDecToHex/

To divide decimal numbers:\n\n1.If the divisor is not a whole number:\n      *Move the decimal point in the divisor all the way to the right (to make it a whole number).\n      *Move the decimal point in the dividend the same number of places.\n\n   2.Divide as usual. If the divisor doesn't go into the dividend evenly, add zeroes to the right of the last digit in the dividend and keep dividing until it comes out evenly or a repeating pattern shows up.\n\n   3. Position the decimal point in the result directly above the decimal point in the dividend. \n\n   4. Check your answer: Use the calculator and multiply the quotient by the divisor.

convert the mixed # to a improper fraction... 2 x 2=4 ,   4+1=5 \n5/2\nthen multiply 5/2 x 26 = 130/2\nreduce 130/2=65

That is right. Just put them in a calculater to check. 2/9=0.22222222 and 8/36=0.2222222. Either they are wrong or you misinterpred the question and it was asking something else. The best way to solve a problem like that is to cross multiply. 2/9=8/? turns into 2*?=8*9.

Use a calculator - numerator divided by denominator will give you the answer.

Start with the fixed part... 2.1 is 21/10.\n\nThe rest of the number is 0.036363636...\nLet's call that x.\n\nx = 0.036363636...\nNotice what happens if you multiply by 100.  I picked 100 because there are two repeating decimals.  If there were 1 you would pick 10, if 3, you would pick 1000, if 4 pick 10000, etc.\n100x = 3.6363636...\n.......x = 0.0363636...\n\nSubtract and the repeating decimals are cancelled:\n99x = 3.6\n\nMultiply by 10 to get rid of the last remaining decimal:\n990x = 36\n\nNow solve for x:\nx = 36/990\n\nNow you just need to add your two fractions:\n21/10 + 36/990\n\nGet a common denominator:\n21*99/990 + 36/990\n\n= (2079 + 36)/990\n= 2115/990\n\nNow reduce:\n= 235 / 110\n= 47 / 22\n= 2 3/22\n\nSo your answer is 2 and 3/22.\n\nYou can also do this in one step, without having to do the two parts:\n100x = 213.63636...\n.......x = .....2.13636...\n\nSubtracting:\n99x = 211.5\n\nMultiply by 10 to remove the decimal:\n990x = 2115\n\nSolve for x:\nx = 2115/990\nx = 47/22\nx = 2 3/22\n\nA final way, if you now understand the underlying math is to just do the following:\n\nPull out the part in front of the decimal (2)... just keep that for later.\n\nThe remaining part is 0.136363636... \nSince we have two repeating decimals, use two nines (99).  However, since it is offset by one fixed digit, add a trailing zero (990).\nTake the fixed digit (1) and subtract it from your number (136, ignoring anything but the first repeat).  This leaves 135.\n\nSo the fraction should be 135/990.  This reduces to 3/22.\n\nSo it becomes 2 and 3/22.\n\nAlways check that the final result makes sense.  Obviously the first part of the mixed fraction should match the decimal (2) and it does.  If you put 3/22 in your calculator, you get 0.1363636...\n\nThere's 3 different methods and they all give you 2 and 3/22.

Just put each number in for x and see what the answer is.  Example : -11/2 + 75 = -5.5 + 75 = $69.50 a unit.

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