how would you explain 1/2 and 1/4 to a 7th grader?

I agree with the food comment.  If you can get a hold of the standard 8-slice pie, you can try the following:\n\nFirst get two volunteers.  Tell them to divide up the pizza in as many ways as they can think of with the following restriction:\n\n(*) The number of slices the first person takes before the second person has a chance to take one is how they must alternate for the remainder of the game.\n\nA win constitutes both volunteers getting the same number of slices.\n\nThen do the same with four volunteers.\n\nIdeally that'll illustrate that a/b can be interpreted as the number of slices that b people will get when we divide a evenly among them (taking 1 slice at a time) or how many groups of b slices (taking b slices at a time) we can get from a.  \n\nIdeally, you can then link multiplication in there somehow by showing that we have a slices or a/b groups of b slices (from the second interpretation) so that a = (a/b)*b.

This is actually elementary math. If you remember the order of operation, it helps. \n\nStep 1: Do the part of the problem in the parenthesis.\n  Example: (4/3)= 1.3333333333 (you get where this is going)\n\nStep 2: Take that answer and multiply it by the named multiplier.\n  Example: 1.33333 * 12= 16\n\nStep 3: Take the result of that transaction and devide it by the named devisor. For this method don't use the fraction way, and don't use a calculator. Do a basic devision problem like you were taught in the 3rd grade using the "bracket."\n  Example: 16/13 = 1  (13 goes into 16 1 time)\n\nStep 4: Subtract the 13 from the 16 and it will give you your remainder.\n  Example: 16/13 = 1   16-13= 3\n\nThe answer when written correctly isn't with a decimal but would look like this- 1 R3.\n\nAlso for a little note for this- Order of operation:\nP (parenthesis)\nE (exponents)\nM (multiply)\nD (devide)\nA (addition)\nS (subtraction)\n\nHope this helps!

ANSWER: 7/8 is greater than 1/9\n\nSOLN:\n\n      1) Multiply numerator of first fraction with denominator of 2nd fraction: (7 x 9 = 63)\n\n      2) Place 63 as the "value" for the first fraction.\n\n      3) Multiply numerator for second fraction with denominator of 1st fraction: (1 x 8 = 8)\n\n      4) Place 8 as the "value" for the second fraction.\n\n      5) Since 63 (the "value" placed for fraction 1) is greater than 8 (the "value" placed for fraction 2), then fraction 1 (or 7/8) is greater.

So lets start with the first one. Make a division problem with 9.0 on the outside and 0.9 on the inside. 9.0 does not go into 0 but does go into nine. Raise the decimal and the answer is ten. It's a bit difficult to explain but here's your answers and when you go in next time ask your teacher for help::\n1. 10 \n2. 8\n3. 4.7\n4. 3.2\nOkay theres a few for you and you should be able to figure out the rest. For the next part you take what x is equal to and divide it by 1.2. So for\n13. 40.8/1.2=34\nAnd do the same for the rest!!\nGood luck!

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.  They consist of a whole number plus a fraction.  To add them you need to convert both mixed numbers to what's called 'improper' fractions, convert those fractions to have the same denominator, and then add the numerators.  You usually convert the result back to a mixed number.\n\nSo, what is 3 1/2?  This is really 3+1/2.  Change the 3 to a fraction:\n\n3+1/2 = 3/1+1/2=6/2+1/2=7/2\n\nNow, do the same with the other number:\n4+1/2=8/2+1/2=9/2\n\nNow add:\n7/2+9/2 = (7+9)/2= 16/2 = 8.\n\nThat's it.  \n\nAlso, think about adding just the whole numbers:\n3+4=7\nand just the fractions:\n1/2+1/2 =1\n\nNow, add those:\n\n7+1=8.

Alright, first write them as improper fractions.\n15/8 and 7/4\n15/8 and 14/8\n30/16 and 28/16\nhow does 29/16 sound?

If the number is a fraction, just divide the top number by the bottom number.  For example, 1/2 = 1 divided by 2 = .5.  Move the decimal point to places to the right = 50%.  If the number is a whole number, just add two zeros and %.  For example, the number 2 = 200%

1/2*1/4*1/10 = 1/80\n\n=> 1/80 of 800 = 800/80 = 10\n\nso, one half of one quarter of one tenth of 800 is 10.

Ok, first you turn them into improper fractions.\n4 3/4 turns into 19/4\n2 1/12 turns into 25/12\n1 1/8 turns into 9/8\n\nThey all have to have the same denominator which would be 24. 19/4 turns into 114/24. 25/12 would be 50/24. 9/8 would be 27/24. Now they all have the same denominator you add them to get 191/24 which is the same as 7&23/24.

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!

lets say the fraction is 6/12\nfind a number that goes into 6 and 12 evenly\nin this case 2,3 and 6 do but you always go with the biggest number that can go into both.\nsix goes into itself once and into twelve twice so the answer is 1/2\nlets say the fraction is 13/6 its an improper fraction and needs to be reduced. thats the case when ever the top number is bigger then the smaller number.\ndivide the bottom number into the top number this time it goes in twice but you still have one left over. you put whatever is left over on top of your original bottom number and the answer is 2 1/6\n\nhope it helps

3 divided by 2/4 is equal to 3 times 4/2.  To divide by a fraction, invert and multiply.\n\n3 divided by 2/4 is equal to 6.

well to make it easy... 2/4+1/4= 3/4 because when you have the same denominator, or the one below the line, you can just add the numerators, or the ones on top. remember that the numerator is over the denominator
