If the value of the new fraction is 1/2, that means the denominator is 2 times the numerator. Let's say, then, that the value of the original numerator is x, the value of the original denominator as y.\n\nThen\n(3+x)/(1+y) = 1/2\n\nmultiply both sides by (1+y)\n\n(3+x)=(1+y)/2\n\nmultiply both sides by 2\n\n2(3+x) = (1+y)\n\nSince we want the original fraction, we want x/y\n\n6+ 2x = 1+y \n\ny = 5 + 2x\n\nsubstituting 5+ 2x for y\n\nx/(5+2x)\n\nInsert any non-zero integer into the above, to get your original fraction. For example, if x=1, then the fraction is 1/7. To check to see if that's correct, let's add 3 to the numerator and 1 to the denominator. We then get 4/8, which is equal to 1/2!\n\nYou could also guess and check this. Start by taking fractions equal to 1/2. Let's start with the smallest after 1/2, which is 2/4. Subtract 3 from the numerator, and 1 from the denominator. Well, we get a negative numerator, so let's skip this one. Okay, then 3/6. Subtracting 3 from the numerator gives 0, which makes the original "fraction" 0, which doesn't work. 4/8: 4-3 = 1 and 8-1 = 7. That means our original fraction could be 1/7, and we've found an answer. Hope this helps!

You must first find the lowest common denominator, then then multiply each top by the same  and then add. Example\n3/5 + 1/2 = 6/10 + 5/10 = 11/10 or 1 1/10

(5/6)-(1/2) = (1/3)\n\n(1/3) / (4/9) = (3/4)

the 2/4\nyou have to reduce the fractions 2/8 = 1/4 and 2/4  = 1/2

just go straight across.\n\nlike:  3/8 x 2/3 = 6/24 which simplifies to 1/4\n\nBecause on the top: 3x2=6 and on the bottom: 8x3=24\nThen 6 goes into itself once and into 24 four times: 1/4

n - 1 1/2 = 3\nAdd 1 1/2 to each side\nn = 3 + 1 1/2\nn = 4 1/2

The demoninator of the fractions are doubling.\n\nSo:\n\n1 1/2 1/4 1/8 1/16 1/32 1/64\n\n1/64 or 0.015625

Multiply the numerators together.  Then multiply the denominators together.  Just go straight across.  If you want, you can simplify the fractions in the beginning so that it's a bit easier.  Then if your answer isn't in lowest terms, I'd simplify that too.  Hope I helped!

I used to also. I'll try to give an explanation: forgive me if I go over anything you already know. Alright, think of it this way: you know how to multiply fractions, correct? Alright, so when you multiply two fractions, such as 1/2 and 3/4, you multiply the numerators (those are on the top) (1x3) and the denominators (those are on the bottom) (2x4) and you have your answer: 1/2 x 3/4 = (1x3)/(2x4) = 3/8. Dividing is just the opposite of multiplication. So if you were dividing 1/2 by 3/4, you just flip over the second fraction and multiply: 1/2 / 3/4 = 1/2 x 4/3 = 4/6. \nHere's an answer that's a bit more advanced but might help you understand this better (at least it did for me): if you have some number, a, over some number, b, it can be written this way: a/b. Now, if you divide it by some other fraction, c/d, it can be written this way: \na/b x 1/(c/d). This is the same as saying that when you divide 6/1 by, say, 2 (which equals the fraction 2/1), it is the same as if you are multiplying 6/1 (6/1, or six divided by 1, equals 6) by 1/2. See for yourself: 6 / 2=3, 6 x 1/2= 6/1 x 1/2 = 6/2 which when you reduce (divide top and bottom by common factor, in this case 2) it equals 3/1, or 3. \n1/(c/d) is the reciprocal of (c/d). The reciprocal basically means you flip the top and bottom: for instance, the reciprocal of 2/3 is 3/2, the reciprocal of 1/2 is 2/1, or 2, the reciprocal of 4/1, or 4, is 1/4, etc. So if you flip over c/d, you get: a/b x d/c, which if a=1, b=2, c=3, and d=4, is exactly the same as what we had above.

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*

if you are dividing 2/3 by 4/5, then multiply 2/3 times 5/4.  When subracting fractions, you must have a common denominator.  For 1/2 minus 3/4, multiply the 1 and the 2 by the donominator of the other (4, in this case) to get 4/8.  For the 3/4, multiply the 3 and 4 by the 2, to get 6/8.  Now you can subtract: 4/8 - 6/8 = 2/8 , which equals 1/4.

The fractions you wrote are actually already reduced fractions; i.e. the gcd(numerator, denominator) = 1\n\nif you were intending to multiply the three fractions, that simplifies to 13/50

That would be like 2/2 is equivalent to 3/3, or 3/4 is equivalent to 6/8.  Equivalent fractions will be eqaul when they are reduced to their lowest form.  1/2 is equivalent to 40/80, the list goes on and on.

Start with demonstrating the multiplication of fractions through physical models.\n\nSplit a rectangle in half.  That is 1 x 1/2... because you are counting that one thing 1/2 time.\n\nThen split the 1/2 into 1/2.  1/2, counted 1/2 time, is 1/4.  See it?\n\nOK, so... through whole numbers you have already demonstrated (and they should already have shown true comprehension of the idea) that division is the inverse of multiplication. So...\n\n\n1/2 divided by 2/3 is the same as 1/2 x 3/2 because that is the inverse. Division of whole numbers is a reduction of value... division of fractions is an increase of value.\n\nAlso, try this with decimals.\n\n1/10 divided by 4.\n\n1/10 divided by 4/1.\n\n1/10 x 1/4 = 1/40.\n\n1/40 = 0.025.\n\n   ____\n4 |0.1     = 0.025.\n\n25 x 4 = 100\n\n2.5 x 4 = 10.0\n\n.25 x 4 = 1.00\n\n.025 x 4 = 0.100\n\nStart to see the pattern now?

First multiply them to get the same number on the bottom, then add. \n\n1/3 times 2 = 2/6  (1/3 and 2/6 mean exactly the same thing.)\n\n1/2 times 3 = 3/6 (1/2 and 3/6 mean exactly the same thing.)\n\nNow you have the same number on the bottom of the fractions and you can add the two top numbers.\n\nadd 2/6 + 3/6 = 5/6!  :)\n\nSometimes you have to try different numbers to multiply each fraction by in order to find a combination that will give you the same number on the bottom for each.

2/6\n3/9\n4/12\n\nJust multiply the same number on both sides, like 1*2/3*2=2/6
