How did fractions develope?

Hiraktokus breaks stick in two pieces, and holds pieces up, says "here is one stick half, and here is another stick half.   Each is a half stick, this is one half stick, and this other is also one half stick."  So it came to pass that stick cut in half is one-half stick. The develope of fractionism. This was not mathematics; this was breaking of stick.

well fractions or math is not complicated mabie you just need some one to explan it to you better fractions simply means less than whole if i have a pizza per say and i cut that pizza in to 8 pieces i eat two and am left with 6 pieces i then have 6/8 of a pizza so now its a fraction hope this helps .

can you elaborate on that? what do you mean by simplify decimals? you can put decimals into fraction form and simplify that.

One way is to construct the rational numbers so that each is written as a fraction that does not need to be simplified.  \n\nBegin with all fractions whose numerator and denomenator sum to 2.  There is only one such fraction (1/1).  Map this fraction to the integer 1\n\n1/1 --> 1\n\nThen consider all fractions whose numberator and denomenator sum to 3.  There are two such fractions:  2/1 and 1/2.  Map these two fractions to the next available integers:\n\n2/1 --> 2\n1/2 --> 3\n\nThen map the three fractions whose numerators and denominators sum to 4 to the next available integers:\n\n3/1 --> 4\n2/2 --> 5\n1/3 --> 6\n\nAnd so forth.\n\nThis algorithm will map all of the rational numbers onto the set of natural numbers.  However, it is a many-to-1, not a 1-to-1 mapping (it maps 1/1 to 1 and also maps 2/2 to 5, but 1/1 and 2/2 have the same value as rational numbers).  You could get around this by skipping over rational numbers that are not simplified fractions.

Mandelbrot developed the mathematics for fractals by studying many different practical applications.  For example, "noise on telephone lines, games theory, linguistics, economy, cosmology, turbulence" (from the link below).

I find that so hard to believe.That's inexcusable at that level of education.I've been in the building trades for 19 years and can add,subtract,multiply and divide fractions in my head.The rules are painfully simple regarding the math.I have a hard time believing anyone could have problems with that.\nAnd not for nothing,but your grammar is pretty bad as well.The question should read "Why do students at the university level still have difficulties with fractions?"

In fraction if the denominators are the same, just add the numerators and copy the denominators, then reduce to lowest term as needed.\n\nExample: 1/2 + 3/2 = 4/2 or 2\nThe numerators are 1 and 3,  adding them will give 4. Then just copy the denominator which is 2. That makes it 4/2, which you need to reduce to lowest term. So 4 divided by 2  (to reduce to the lowest term) so the answer is  2.\n\nIf the denominators are different, then find a common denominator (the least number that can be divided by both denominators) then divide it with the denominator and multiply with the numerator. Then when your numbers are already expressed on fraction with the least common denominator, proceed to adding the numerators and copy the denominator.  \n\nExample:\n\n1/2 + 2/3   (the common denominator will be 6)\n>>1/2 becomes >> 6 divided by 2 = 3  X 1 = 3 -->> 3/6\n>>2/3 becomes >> 6 divided by 3 = 2  X 2 = 4 -->> 4/6\n\nProceed to addition:\n3/6 + 4/6 = 7/6 (divide 7 by 6 to get the lowest term) = 1 and 1/6 is the answer.\n\nGood luck!♥

alright - the fractions you have given me are called unlike fractions which means they have a different denominator. to compare fractions the first thing you need to do is make them like(same denominator) -now,a fraction remains the same if you multiply the numerator and denominator with the same number. So look at your denominators-3,5,4,8. you need to find a number that is a common multiple for all these numbers-if you look at it, you dont see any immediate number as such-so just multiply all of these numbers to get their common multiple(ideally you should look for the lowest common multiple) which gives 480. now,multiplying the numerators with the corresponding numbers we get the following fractions: 320/480,192/480,360/480,300/480.\nnow that you have all the like fractions, though these may look different, they are actually same as the original fractions that you gave me. all you have to do now is arrange them in ascending order of numerators which gives:\n192/480 , 300/480 , 320/480 , 360/480\nnow writing the corresponding original values,your answer is:\n2/5 , 5/8 , 2/3 , 3/4\n\nthis is one method,another method involves direct division and then comparing the value, but you will get the same answer

A number that can be written as a fraction.

One of the easiest ways to do it is to change the fraction so the denominator is 100.  For example, say you want to find the decimal form of 2/5.  If you multiply 5 by 20 you'll get 100, so multiply the numerator by 20 and the denominator by 20 and you get 40/100.  To change it to a decimal, place the decimal point behind the number you just came up with, so 2/5 in decimal form would be .40.

Multiplying the denominators of all the fractions would be the easiest method.\n\nHowever, if the numbers are really big and you prefer working with small ones (e.g. if you do not have a calculator), you can first find the lowest common multiple (LCM).

The steps for adding two fractions:\n\n1) reduce both fractions  (not strictly necessary, as long as you reduce in the end)\n2) give them both the same demoninator (the bottom number)\n3) add the top numbers (the numerators)\n4) reduce the answer\n\nSo, step one is already done.\n\nStep two is to give them a common (the same) denominator.  So what number should that be?\n\nIt's going to be the product of both denominators.  so 3 * 8 = 24.  So that's our common denominator.\n\nWhat you are going to do is to multiply the top and bottom half of each fraction by the same number (which is okay, it's equivilant to multiplying by 1) so that the bottom number is 24.  So for the left fraction, we will multiply the top and bottom by 3.  So we get (3 *3)/(8 * 3), which is 9/24.\n\nAnd now we multiply the second fraction, top and bottom, by 8.  so (2 * 8)/(3 * 8) = 16/24.  Now that both fractions have the same denominator, we add them by adding the top numbers, and putting that over the common denominator.  So 9 + 16 = 25, so we get 25/24.\n\nThis is technically acceptable, but teachers will probably want you write this as 1 and 1/24th.

The horizontal line has no other name other than its description, the horizontal fraction bar.  This way of writing fractions was invented by the Arabs (perhaps al-Hassar around the year 1200).\n\nThe diagonal line sometimes used to write fractions,e.g. 1/2, what we call a forward slash, is also called a virgule or solidus.  It was developed because the horizontal bar is more complicated when printed.  (For example, here on Yahoo Answers, fractions are written with the slash because there is no way that I am aware of to make horizontal bar fractions without resorting to multiple lines and careful spacing.)\n\nAddendum:  No, it is not called the divisor.  The divisor in mathematics is a number which is divided into another number.  In fractions, the denominator would be the divisor.

ok when adding fractions you find the common denominator on the bottom #s of the fraction then when you have the common denominator you see how much each goes into and add them\n\n1  3\n2  4 so them u go 2 goes into 4 (2 x) then x # by 1\n+\n3  3\n4  4   so 4 goes into 4 once, then x 3 = 3\n\nthen you add 3+3=6 so answer is 6\n                                4\nu do same with subtracting fraction but in the end instead of adding the top #s you subtract

YOu cannot change improper fractions to proper fractions. They may be changed to mixed numbers, whole numbers, of mixed decimals\n\n27/2= 13 with a remainder of 1 so you write is as 13 and 1/2 or 13.5

the most important thing to remember when adding and subtracting fractions is to find a common denominator. The only way to get good at doing fractions is to do them.
