divide 343 by 60 to get the number of minutes and the remainder are the seconds

Divide numerator and denominator by 9... your answer is:\n1/3\n\nYou can't reduce this any further.

basically, if your looking for the highest the number must be near to 1. or another way is to make the denomether(dunno the spelling) the same. like 3/4 and 2/3 find the LCD(least common denomither) it will be 12. so..... 3/4= 9/12 and 2/3= 8/12 so if thats the case 2/3 is higher

use a calculator, or do it the old fashion way. first u divide 13 into 80 which euals 6 with a remainder of 2 then u bring the 9 down and 13 goes into 29 2 times. the answer in 62 with a remainder of 3or 62 3/13

Make the mixed fraction into a fraction like 1 3/4 converts to 7/4  Then divide the bottom number into the top number

Find the least number that each can be divided by....Such as(example) 1/2+ 1/3= the lowest denominator would be 6 since 2x3=6 and 3x2=6 so both can be multiplied to make that number. So if you use that common denominator of 6 the problem would be set up like this 3/6+2/6=5/6

Not necessarily.  If the answer to a division problem is 7.5, then the answer is 7 and a half (half of what you're dividnig by).\n\nExample- 15 divided by 2 is 7.5, but the remainder in this problem is 1, not 5 (1 is half of 2).

The only thing I can come up with off the top of my head is that you can use least common factors to determine the lowest common denominator for adding/subtracting fractions.  For example, 2/15 + 5/36 ... the lowest common denominator is 3*5*3*2*2 = 180 (using the least common factors of 15 = 3*5 and 36 = 3*3*2*2).  Not terribly "real life" but a "real application" nonetheless.

You end up with a remainder, so it's not pretty, but you should be able to do long division and get:\n\n3x^2 - 4x + (16/3) - 23/(3*(3x+2))

If x = original number\nand\nR1= remainder of x/3\nR2= remainder of x/5\nR3= remainder of x/7\n\nThen  x = (R2 * 21) + (R3 * 15) - (R1 * 35)\n\nSo for your example of 26:\nR1 = 2\nR2 = 1\nR3 = 5\n\nX = (1 * 21) + (5 * 15) - (2 * 35)\n   = 21 + 75 - 70\n   = 26\n\nNotice how the remainder of one number relates to the multiple of the other two. Also, I think you need to start at 7 instead of 3, because there will be fractions and no remainders for the numbers less than 7.\n\nEDIT:\n\nIf you look at the formula again, you will see that it works for your example, also!  =)\n\nBe careful where you plug in your numbers; they aren't in order.
