where can i get a complete list of common fractions?

There are an infinite number of fractions, so a list of common ones is out of the question, because a "common" fraction would involve some sort of average, which would involve division by infinity; an impossibility.\nso, nowhere.

There is a book called Fraction Pizzas.  I've used it before...great resource.  Can't remember the author off hand and the author wasn't listed on Amazon.  They did have the ISBN number.  You can use this to order from another source...or it would help librarians at your local library.  The ISBN number is  0768209633

You should go to www.AAAMath.com  good luck

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'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?

I haven't done partial fractions in a while, so you might want to check this: \n1/(x+3) - 2/(x+3)^2 + 5/(x-7)

Find the commone denominator, and then convert both fractions into their equivalents using that denominator.  For example, 1/2 can also be written as 2/4, 3/6, 4/8, etc.  Once both fractions have the same denominator, just add the numerators and reduce.\n\nTo add 1/3 + 4/9, the common denominator is 9.  4/9 is already done, so you would just need to change 1/3.  3 goes into 9 3 times, so multiply the top and bottom by 3 (or multiply by 3/3, which is the same as multiplying by 1 - perfectly legal in math :) 1/3 * 3/3 = 3/9\n\nNow you have 3/9 + 4/9 = 7/9 --- this cannot be reduced any further.

find the common denominator\nmultipy the top and bottom of the fraction so the denominators are equal and then add the numerator

What you want to do is factor out the same values from the numerator and denominators.  \n\nThe order in which you factor these out does not matter, the key is to continue to factor them out until there is nothing else to factor out.\n\nFor example you can factor out a^8 by turning it into:\n\n36 * (a^8) * (b^4) * 1/2\nover\n27 * (a^8) * a * (b^6) * 1/3\n\nsince (a^8) over (a^8) = 1 you can cancel them out leaving you with:\n\n36 * (b^4) * 1/2\nover \n27 * a * (b^6) * 1/3\n\nwe do the same factoring for b where we can factor out a (b^4):\n\n36 * (b^4) * 1/2\nover \n27 * a * (b^4) * (b^2) * 1/3\n\ncanceling the (b^4)s we get:\n\n36 * 1/2\nover\n27 * a * (b^2) * 1/3\n\nYou can then further reduce the fraction by multiplying out the 36 * 1/2 and the 27 * 1/3:  leaving you with:\n\n18\nover \n9 * a * (b^2)\n\nAs you can see now you can factor out a multiple of 9 leaving you with:\n\n2\nover\na*b^2
