order these fractions form greatest to least. Use inequality signs. 2/4, 1/4, 2/3, 7/8, 1/3, 3/5?

Give them all a common denominator and then it is easy to see which is biggest.  The least common denominator of 4, 3, 8, and 5 is 120.\n\nSo for 2/4, 4 goes into 120 30 times, so multiply top and bottom by 30.  2/4 = 60/120.  For 7/8, 8 goes into 120 15 times, so mutiply top and bottom by 15.  7/8 = 105/120.\n\nKeep going this way\n2/4 = 60/120\n1/4 = 30/120\n2/3 = 80/120\n7/8 = 105/120\n1/3 = 40/120\n3/5 = 72/120\n\nNow order from greatest to least\n\n105/120 > 80/120 > 72/120 > 60/120 > 40/120 > 30/120\n\nAnd put back to the original fractions\n\n7/8 > 2/3 > 3/5 > 2/4 > 1/3 > 1/4

Use a division sign in parentheses. That way three fourths will look like (3/4).

I would recommend changing 3 1/2 into an improper fraction.  \n\nSo 3 1/2 will become 7/2.\n\nNow we are multiplying 7/2 and 3/4.\n\nRemember when multiplying fraction we say top times top and bottom times bottom.\n\nSo we will have (7 x 3) / (2 x 4), which is 21/8.\n\n21/8 as a mixed number becomes 2 5/8.\n\nHope this helps!

Change them to improper fractions\n1 1/4 = 5/4\n6 2/3 = 20/3\n5/4 divided by 20/3 equals 5/4 times 3/20\n(5/4)(3/20) = 15/80 = 3/16\n\n20 divided by 6 2/3 = 20 divided by 20/3 = \n20 times 3/20 = (20/1)(3/20) = 60/20 = 3\n\n4/5 divided by 4/5 is 1.\n(Any nonzero number divide by itself is always 1.)\n\n16 1/2 divided by 6 2/3 = 33/2 divided by 20/3 = \n33/2 times 3/20 = (33/2)(3/20) = 99/40\n\n28 divided by 4/5 = (28/1)(5/4) = 35

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.

First you try to get all of the parts to have same denominator (which looks like 8 is what you need).\nSince the first and the last are already w/ 8, then u need to * and / the middle number with 2.\nSo you get:\n2/8-4/8+5/8\nnext you can write:\n(2-4+5)/8\nand that's 3/8\n=>\n2/8-2/4+5/8 = 2/8-4/8+5/8 = (2-4+5)/8 = 3/8

You use cross multiplication.\n1/2, 5/8, 6/*, 3/4 \n\nYou multiply the numerator of one fraction to the denominator of the other fraction you're comparing it with. For example, you cross multiply 1/2 and 5/8.\n\n1*8 = 8 so lets say 1/2 got 8\n5*2= 10 so 5/8 got 10. Therefore, 5/8 is greater than 1/2

You can subtract them by making like denominaters:\n\n3/4-1/2+2/5\n\nThe denominaters all go into 20\n(whatever you do to the bottom you have to do to the top!)\n  3x5=15 4x5=20 \n\n15/20-1/2+2/5\n\n  1x10=10 2x10=20\n\n15/20-10/20+2/5\n  \n  2x4=8 5x4=20\n\n15/20-10/20+8/20\n\nYou only add the numeraters\n\n15/20-10/20=5/20\n\n5/20+8/20=13/20\n\n\nOr do it by decimals.\n\nTo change a fraction into a decimal, you divide the numerater by the denominater. *=divide\n\n3*4=.75\n1*2=.5\n2*5=.4\n\n.75-.5=.25\n.25+.4=.65\n\nTo change .65 back to a fraction, you move the decimal over two places, 65, so now you put it over a hundred, because you moved it past the hundreth's place. 65/100. Now simplify. Divide both by 5, (becaus eit goes in there evenly.) Now you have 13/20. (When you move the decimal place and you have \n.345, you get 34.5. You can't move it three. It's the rules!)

First compare the whole numbers.\nList them in order by their whole numbers. \nNext, if more than one has the same whole number, then you need to compare the fractions.\nTo compare the fractions, you will need a common denominator.\nAfter you have a common denominator, you just compare the numerators.\nExample:  List in order from least to greatest.\n5 1/2, 8 5/6, 3 7/8, 4 1/6, 8 3/4, 3 15/16\n\nFirst list them in order by the whole numbers.\nThe whole numbers are 5, 8, 3, 4, 8, 3\nIn order, they are\n3, 3, 4, 5, 8, 8  (Not so hard so far, is it?)\nNow go ahead and put the fractions with them.\n3 7/8, 3 15/16, 4 1/6, 5 1/2, 8 5/6, 8 3/4\nNow since you have two mixed numbers with 3, you must compare the fractions.\nFor the whole number 3:  Which fraction is smaller 7/8 or 15/16?\nTo compare them, you will need a common denominator.\nThe common denominator of 8 and 16 is 16.\nSince 8 times 2 is 16, you need to multiply the top and bottom by 2.\n7/8 = (7*2)/(8*2) = 14/16\nWe now have a common denominator.  Now which one is smaller, 14/16 or 15/16?  Since 14 is smaller than 15, we conclude that 7/8 is smaller than 15/16\nSimilarly for the mixed fractions with whole number 8:\nWhich one is smaller, 5/6 or 3/4\nHere the common denominator will be 12\n5/6 = (5*2)/(6*2) = 10/12\n3/4 = (3*3)/(4*3) = 9/12\nSince 9 is smaller than 10, 3/4 is smaller than 5/6\nThe answer is\n3 7/8, 3 15/16, 4 1/6, 5 1/2, 8 3/4, 8 5/6

between 7/12 and 3/4 (which is 9/12) you have 8/12 which reduces to 2/3\n\nbetween 3/4 (which is 9/12) and 11/12 you have 10/12 which reduces to 5/6\n\nHope this helps.

1/30 n^5 - 5/8 n^4 + 53/12 n^3 -107/8 n^2 + 371/20 n - 8 works.\n\nI don't think you'll find anything nicer.

29x - 515 < -14(8 - 3x) given\n29x - 515 < -112 + 42x distribute\n-515 < -112 + 13x subtract 29x from each side\n-403 < 13x add 112 to each side\n-31 < x divide by 13\nx > -31 just turn it around because it looks better\n\n(the answer above this one would be correct, but you need to reverse the direction of an inequality when dividing by a negative number.)

Q2 and Q3: This is going to be easier to understand than to explain, so I'll just show you...\nfor  1/5, 1/4, 1/3\n\n1/4 = (1+1)/(5+3)\n\nQ4: use 1/2 and 3/5 this time...\n1/2 - 3/5 = 1/25\nand \n2*3 - 1*5 = 1\n\nAs for showing work, I'd look at a bunch of examples and just see the differences between the consecutive numbers. \n\nBest of luck!

Technically there are only 4 answers that will work, and they all rely on parentheses to modify the natural precedence rules:\n\n(5+5/5)*5\n(5/5+5)*5\n5*(5+5/5)\n5*(5/5+5)\n\nAs you can see they are all variations on (5 + 1) * 5, where you use 5/5 = 1.  So there is really just one answer.\n\nYou can easily solve problems like this yourself using the link below...\n\nFor example, can you make 24 using 3, 3, 8, 8?  Try it before you cheat... also, note that the solver allows % (mod) as an operator, so you may have to filter out those results.
