3/5 + 2/5= 5/5=1\nfor addition and subtraction you need to find the common denominator!\nfor multiplication you just multiply\nfor division you do the reciprocal and then multiply!

in order to figure this out, you first have to find the decimal of the numbers. to do this follow these steps:\n\n1-divide the numerator by the denomintaor, therefore, recieving the decimal\n\n3 divided by 8= 0.375\n\nyou have to round the number if it has more than two decimal places \n\n0.375=0.38\n\nthen, you multiply the decimal you got by 100, then you get your percent\n\n0.38 x 100 = 38\n\n38=38 %\n\nhope you understand good luck :)

alright - the fractions you have given me are called unlike fractions which means they have a different denominator. to compare fractions the first thing you need to do is make them like(same denominator) -now,a fraction remains the same if you multiply the numerator and denominator with the same number. So look at your denominators-3,5,4,8. you need to find a number that is a common multiple for all these numbers-if you look at it, you dont see any immediate number as such-so just multiply all of these numbers to get their common multiple(ideally you should look for the lowest common multiple) which gives 480. now,multiplying the numerators with the corresponding numbers we get the following fractions: 320/480,192/480,360/480,300/480.\nnow that you have all the like fractions, though these may look different, they are actually same as the original fractions that you gave me. all you have to do now is arrange them in ascending order of numerators which gives:\n192/480 , 300/480 , 320/480 , 360/480\nnow writing the corresponding original values,your answer is:\n2/5 , 5/8 , 2/3 , 3/4\n\nthis is one method,another method involves direct division and then comparing the value, but you will get the same answer

.47\n\n47/100 \n\nSo that you understand it, everytime you want to change a percentage to decimal, you take out the % and divide it between 100\n\nFor decimals, you take out the % and write the number you have above (here/100) 100\n\nHope it helps, have a nice day

The first thing you need to do is get the fractional exponent out of the denominator. You do that by multiplying top and bottom by x to the 1/6th power.\n\nSo now you have 2^ 4/3 * x^ 3/2 and all of that is over x

Try 1 ÷ 3\n\n1/3 = 0.33333.....\n\n~ ♥ ~

the easiest way to add and subtract fractions is first finding the LCD (least common denominator)\n\nfor in the instance of lets say 2/5 + 1/4 the LCD from 5 and 4 is 20.  so you would multiply the top number by the same amount as it would take to get each fraction to equal whatever the LCD is.\n\n2/5 * 4/4 = 8/20 and 1/4 * 5/5 = 5/20 \n\nif you notice the fraction you are multiplying by can be reduced to 1 and therefor you are not changing the amount, you are multiplying by 1. \n\nthen take your new fractions and ad or subtract across the top.\n\n8/20 + 5/20 = 13/20 \n\nafter you find this solution reduce as neccesarry.\n\nhope this helps.

[3/(8a)]+[1/(-8a)]\nSet it up as a fraction.\n\nMove the negative on the second term.\n\nIt should look like this. [click link] \nhttp://img139.imageshack.us/img139/1227/fract2sp.jpg\n\nAdd the numerators. Result: http://img227.imageshack.us/img227/2604/fract24ww.jpg\n\nReduce the fraction. Result:\nhttp://img100.imageshack.us/img100/7498/fract35ir.jpg\n\nThat's your answer.

Take the decimal number and multiply it by a number.  Then take the sum and divide it by the multiplier.\n\nI'm supposing you know the decimal number you want to express in a fraction.

Make 2 7/15 an improper fraction, flip it over to its reciprical and mulitply the two.\n\nBoy...I hope I got that.  *bits fingernails*

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

The answer is 1/2. To solve it... use algebra. Use X to represent the unknown fraction. Turn the word problem into a numerical expression. It will look like this: 4(X/5) x X = 1/5.    the little x is times. simplify and you get 4X^2/5= 1/5. then simplify again and you get 4x^2=1 Then x^2= 1/4 then x=1/2 ta da!

decimals you just move over two places:\n\n.00124= .124 %         .245= 24.5%\n\n\nfractions you make denominator 100 and the top is the percent or else change fraction into a decimal and use the above:\n\n1/2= 50/100= 50 %        3/8= .375= 37.5 %

Add 3/8 to each side to get A by itself:\n\nA = 3/8 - 7/12\n\nThen you need a common denominator to add the two fractions together.  The common denominator is 24, to get that multiply 7/12 by 2/2 (which is one) to get 14/24.  7/12 = 14/24.\n\nDo the same for 3/8 multiply it by 3/3 (which is one) to get 9/24.  3/8 = 9/24\n\nSo 9/24 - 14/24 = -5/24\n\nA= -5/24

Let me give you a hint.\nDivide 2.49 by 12.\nThen multiply by 5.\n\nOf course you could use fractions?

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

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.
