can anyone help me with fractions? how to I add whole and mixed fractions? eg. 4 5/6 + 2/5?

you have to change the mixed fraction into a improper fraction 6*4+5 = 29 that will be your numerator and 6 will be you denominator the you have to find a common denominator of 6 and 5 that would be 30 so 30 will be the denominator in your answer what ever you do to the bottom you have to do to the top so you would multiply 29*5 and 2*6 and those are your numerators so it would be 145/30 + 12/30 = 157/30 and then you would reduce

In order to add or subtract fractions, you must have common denominators; that is, the bottom number has to be the same. You can change the bottom number of a fraction by multiplying the entire fraction by 1. The fact that n/n=1 for all values of n except 0 makes this a lot easier. So, let's take your problems. The easiest way to get a common denominator is to multiply the first fraction by the second denominator, and the second fraction by the first denominator. (This won't be the Least Common Denominator, though. That involves factoring the numbers.)\n\n1) (4/7) + (7/p)\nSince 4/7 doesn't reduce (we can't tell 7/p), we'll want to get 7p as the common denominator. \n(4/7)(p/p) + (7/p)(7/7)\n(4p/7p) + (49/7p)\nNow that we have the same denominator, we just add the numerators. Whoops. Since we don't know what (p) is, we have to leave it as\n(49 + 4p)/7p for p != 0 . (Oh, yeah. != is one of the ways of saying "does not equal" on the computer. You might also see it as =/=, which looks more like what you would write.)\n\n2) 4/6 - 2/k. First, let's simplify 4/6 to 2/3, this will keep things easier later on. \n2/3 - 2/k. Now, a denominator we can use is 3k\n(2/3)(k/k) - (2/k)(3/3)\n2k/3k - 6/3k\n(2k-6)/3k, for k!=0\n\n3) 2=5 + 6/k. \nOK, this one solves a bit differently. We need to find a value that makes the statement true. First, let's get all the ks on one side, and everything else on the other (remember, a=b therefore b=a)\n6/k = -3\nNow, to get from here to there, we need to get the k out of the denominator. There's a property of multiplication that lets us do this, the shorthand for it is (if a=b, then ac=bc). So, we'll multiply through by k...\n6 = -3k.\nAnd now, we need to get k by itself. Normally, I'd suggest dividing by -3. But I don't particularly like division, so I'm going to tell you to multiply by the reciprocal of -3; Which is 1/(-3) or -1/3.\n6(-1/3) = (-1/3)-3k\n-2 = k

Just cross of like terms in the numerator and the denominator and see what is left.  like in the first problem the numerator and the denominator share two two's and a 3, so by crossing them off you are left with 4/7.  You can do that since 2/2 is one, and likewise with other similar fractions, and when you multiply by one you always get the same fraction.

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 :)

to write a % as a fraction, just put it over 100. e.g.  60%  + 60/100.\n(This simplifies to 6/10) Then, to convert it to decimals,  put a decimal point in front of it.  e.g. 60% = 60/100 or .6

6 2/8 *4  becomes (6 1/4)*4 or 6.25*4=25\n\nShould view it as an elementary school fraction:  6 AND 2 eighths times 4 is 25.

Writing 1.25 as 1¼, which means 1 and a quarter, is called a mixed number.\n1¼ = 1 + ¼\n\nThis is generally bad notation to use in algebra, because every other time a number, pronumeral or expression is next to another it means multiplication. eg...\n\n2x = 2 * x\n2(2 + x) = 2 * (2 + x)\n4! = 4.3.2.1 = 4 * 3 * 2 * 1\n\nA better way to write mixed numbers is as improper fractions, where the numerator (top number) is greater than the denominator (bottom number). eg...\n\n3¼ = 3 + 1/4 = 12/4 + 1/4 = 13/4\n\nThis way, there is no ambiguity.

Since when you multiply the top and bottom of fractions by the same number, you can find a common denominator for them. For example, 1/2 of a pie is the same as 2/4 or 3/6 of a pie. When you multiply 4/7 by 5/5, you get 20/35. Do the same thing for 2/5. Then you have 20/35 + 10/35. Add the 20 and then 10, and you get 30/35. Then that can be divided on top and bottom of 5 to get 6/7, which is your ANSWER! :)

I'd start by pairing them up a bit to simplify common denominators.\n0/1 = 0\n1/2+3/4+7/8 = 4/8+6/8+7/8 = 17/8\n2/3+5/6+8/9 = 12/18+15/18+16/18 = 43/18\n4/5+6/7 = 28/35+30/35 = 58/35\n\nNow there's only 3 fractions, 58/35+43/18+17/8.  Time to find the grand common denominator.  I'm using underscores to indent since spaces get stripped out.\n_35\nx18\n- - -\n280\n35\n- - -\n630\n\n_630\nx__8\n- - - -\n5040\n\nBut since 2 will go into 630 and 8, we can reduce that by half, 2520.\nNow, find the multipliers we want through long division to use against the numerators.\n\n_____72\n35 | 2520\n___245\n___- - -\n____070\n_____70\n_____- -\n______0\n\n\n____140\n18 | 2520\n___18\n___- -\n___072\n____72\n____- -\n____000...\n\nThis is too tedious after all.  Guess I'll keep going, but I'm going to use my calculator a little, now.\n\n2520/35=72\n2520/18=140\n2520/8=315\n\n58/35+43/18+17/8 =\n4176/2520+6020/2520+5355/2520 =\n15551/2520\n\nAnd that's my final answer.  What do I win?

Those are mixed numbers containing whole number and a fraction.\n8 1/2=8+1/2=8.5\nSimilarly 1 1/4=1+1/4=1.25 and others.

The denominators need to be the same before you add fractions. Simply multiply each fraction (top and bottom) by the denominator of the other fraction. This doesn't change their values.\n\na/b + c/d = ad/bd + bc/bd\n\nThen you can add the numerators safely!\n\n= (ad + bc) / bd\n\n;?)\n\n\nAdditional details: Multiple fractions - \n\nYeah, the simple rule is to multiply by all of the denominators, e.g.\n\n1/2 + 4/7 + 3/5 =\n\n1x(5x7) / 2x(5x7)  +\n4x(2x5) / 7x(2x5)  +\n3x(2x7) / 5x(2x7)  =\n\n35/70  +  40/70  +  42/70 =  117/70 =  1+(47/70)\n\nIn some cases you can use a smaller denominator, by finding the "lowest common multiple" of the original denominators, e.g.\n\n1/6 + 2/3 + 5/12\n\nIn this case, you can easily convert all the fractions to n/12, rather than n/216 (which you would get by 6x3x12) which keeps the sum simpler\n\n( 2x1 / 2x6 )   +   ( 4x2 / 4x3 )   +   ( 5/12 )  =\n\n2/12  +  8/12  +  5/12  =\n\n15/12  =  1+ 3/12  =  1+ 1/4\n\nIf you had stuck to the simple method I first described, your sum would have finished up:\n\n36/216  +  144/216  +  90/216  =  270/216\n\nYou'd have to factor this out to simplify it:\n\n270/216  =  1 + (54/216)\n\n=  1 + (2.3.3.3/2.2.2.3.3.3)\n\n=  1 + (1/4), same answer by a different route

The fractions you wrote are actually already reduced fractions; i.e. the gcd(numerator, denominator) = 1\n\nif you were intending to multiply the three fractions, that simplifies to 13/50

Convert the fractions to a common denominator which is 24\n2/3 = 16/24\n3/8 = 9/24\n5/12 = 10/24\n\nThen add them up. \n16 + 9 + 10 = 35 or 35/24 \n\n35/24 = 1-11/24

I used to also. I'll try to give an explanation: forgive me if I go over anything you already know. Alright, think of it this way: you know how to multiply fractions, correct? Alright, so when you multiply two fractions, such as 1/2 and 3/4, you multiply the numerators (those are on the top) (1x3) and the denominators (those are on the bottom) (2x4) and you have your answer: 1/2 x 3/4 = (1x3)/(2x4) = 3/8. Dividing is just the opposite of multiplication. So if you were dividing 1/2 by 3/4, you just flip over the second fraction and multiply: 1/2 / 3/4 = 1/2 x 4/3 = 4/6. \nHere's an answer that's a bit more advanced but might help you understand this better (at least it did for me): if you have some number, a, over some number, b, it can be written this way: a/b. Now, if you divide it by some other fraction, c/d, it can be written this way: \na/b x 1/(c/d). This is the same as saying that when you divide 6/1 by, say, 2 (which equals the fraction 2/1), it is the same as if you are multiplying 6/1 (6/1, or six divided by 1, equals 6) by 1/2. See for yourself: 6 / 2=3, 6 x 1/2= 6/1 x 1/2 = 6/2 which when you reduce (divide top and bottom by common factor, in this case 2) it equals 3/1, or 3. \n1/(c/d) is the reciprocal of (c/d). The reciprocal basically means you flip the top and bottom: for instance, the reciprocal of 2/3 is 3/2, the reciprocal of 1/2 is 2/1, or 2, the reciprocal of 4/1, or 4, is 1/4, etc. So if you flip over c/d, you get: a/b x d/c, which if a=1, b=2, c=3, and d=4, is exactly the same as what we had above.
