Talk:fraction

Is definition 4 a mistake? It says "part of a particular society or group." but it seems to me this is a faction. I don't have a paper dictionary to hand at the moment. Visctrix 10:08, 26 August 2005 (UTC)

In one of your definitions you used the word "ratio" and "integer" to help define a fraction. Ratio usually is defined and worked with in the fifth grade and integer is a sixth grade subject, while fraction is defined and worked with in the third and fourth grades in most elementary school mathematics textbooks. It has been that way for at least 30 years. You may want to check that out in k-12math.info [1] . Jim Kelly

missing definitions.

A rational function can be thought of as a fraction where the numerator and denominator are functions in their own right. More than, "thought of", this usage is common in classrooms. The arithmetic term described is actually the definition of a rational number. Fraction has a broader sense, for instance. 1.2/3 is a fraction, though it does not meet the definition as currently stated. 134.29.231.11 18:56, 20 September 2011 (UTC)

Correct definition with "integer"

With a non-integer numerator or a non-integer denominator, simplify a fraction would be meaningless. So the following definition is wrong.

Template:arithmetic A ratio of two numbers, the numerator and the denominator, usually written one above the other and separated by a vinculum (horizontal bar)

With the word "integers" instead of "numbers", the following definition is correct.

Template:arithmetic A ratio of two integers, the numerator and the denominator, usually written one above the other and separated by a vinculum (horizontal bar)

No source says integer. A fraction with integers is a special type of fraction - a common (or vulgar) fraction. pi/4 is a fraction, as is sqrt(2)/2, 1.5/2 and 1 1/2 /2. This was pointed out in the edit summary AND even in the previous section here --JimWae 09:45, 24 September 2011 (UTC)
