In the second step, they were divided by 3. The final result, 4 / 3 , is an irreducible fraction because 4 and 3 have no common factors other than 1. The original fraction could have also been reduced in a single step by using the greatest common divisor of 90 and 120, which is 30. As 120 ÷ 30 = 4, and 90 ÷ 30 = 3, one gets
Thus the fraction 3 / 4 can be used to represent the ratio 3:4 (the ratio of the part to the whole), and the division 3 ÷ 4 (three divided by four). We can also write negative fractions, which represent the opposite of a positive fraction. For example, if 1 / 2 represents a half-dollar profit, then − 1 / 2 represents ...
Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:

In the case of two nested square roots, the following theorem completely solves the problem of denesting. [2]If a and c are rational numbers and c is not the square of a rational number, there are two rational numbers x and y such that + = if and only if is the square of a rational number d.
Given a quadratic polynomial of the form + + it is possible to factor out the coefficient a, and then complete the square for the resulting monic polynomial. Example: + + = [+ +] = [(+) +] = (+) + = (+) + This process of factoring out the coefficient a can further be simplified by only factorising it out of the first 2 terms.
Simple English Wikipedia was launched on September 18, 2001. [1] [2]In 2012, Andrew Lih, a Wikipedian and author, told NBC News' Helen A.S. Popkin that the Simple English Wikipedia does not "have a high standing in the Wikipedia community," and added that it never had a clear purpose: "Is it for people under the age 14, or just a simpler version of complex articles?", wrote Popkin.
For instance, instead of writing kan for "can", the Gregg stenographer just writes k. [4] These brief forms are shown on the adjacent image. There are several others not shown, however. For instance, "please" is written in Simplified and before as simply pl, [13] and "govern" as gv. [14]
