what is the lcd(least common denominator) of 1/4, 7/8?
815179
8 because 7/8 cannot be reduced to anything more simple, so the simplest fraction that can be multiplied to 1/4 to get a multiple of 8 on the bottom is 2/2 resulting in 2/8.  Therefore the lcd is 8

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?

simply subtract 7 from both sides. This leave you with\n\nx<_3

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

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*

Find the lowest common denominator (LCD).\n\ni.e.  1/2 + 1/3\n\nLCD = 2*3 = 6\n\n(1*3)/(2*3) + (1*2)/(3*2) =\n\n3/6 + 2/6\n\n5/6

You have to first find a common denominator for the bottom number of the fractions  ie 4 and 8.\n4 and 8 both go into 8 so 3/8 stays the same.  To change 1/4 to an   */8 fraction you need to x the top number by the same number as the bottom...so do 2 x 1 =2  \nSo 1/4  is the same as 2/8.\nNow you can subract 3 3/8 from 7 2/8 very easily.

the answer is the lowest common multiple of 2,3,4,5,6,7,8,9\n\nwhich is 2.2.2.3.3.5.7=2520

19/4, 4 3/4, 4.75\n\nPick one.

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.

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 common multiple for 4 and 8.  It is 8.\nMultiply everything by 8\n8(10x) - 8(1/4) = 8(9x) + 8(3/8)\n80x - 2 = 72x + 3\nSubtract 72 x from each side\n8x - 2 = 3\nAdd 2 to each side\n8x = 5\nDivide each side by 8\nx = 5/8

LCD: 1. Their LCD is one because there numbers can only multiply 1 and get the same answer.

Hi Kasey \n\nchoose " 12 " as LCD \n5/6+1/4 = \n( 2 * 5 ) + ( 3 * 1 ) / 12 =\n( 10 + 3 ) / 12 =\n13 / 12 =1 1/12\nOR\n1.083 ( a bar over 3 }\n\nGood Luck sweetheart
