Of polynomials[ edit ] One can define the division operation for polynomials in one variable over a field. Then, as in the case of integers, one has a remainder.

The remaining three fourths are shown. Dotted lines indicate where the cake may be cut in order to divide it into equal parts.

A fraction from Latin fractus, "broken" represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

A common, vulgar, or simple fraction examples: Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals. We begin with positive common fractions, where the numerator and denominator are natural numbers.

The numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. The denominator cannot be zero because zero parts can never make up a whole.

A common fraction is a numeral which represents a rational number. That same number can also be represented as a decimal, a percent, or with a negative exponent.

An integer such as the number 7 can be thought of as having an implicit denominator of one: Other uses for fractions are to represent ratios and division.

The non-zero denominator in the case using a fraction to represent division is an example of the rule that division by zero is undefined. We can also write negative fractions, which represent the opposite of a positive fraction.

The test for a number being a rational number is that it can be written in that form i.Let’s go back to our example fraction 22/7, and think about it in terms of a division problem instead: 22 divided by 7.

How can we interpret this problem? Well, imagine you have a single 22 meter long stick that you need to divide into 7 equally sized pieces.

The non-zero denominator in the case using a fraction to represent division is an example of the rule that division by zero is undefined. We can also write negative fractions, which represent the opposite of a positive fraction.

For example if 1 / 2 represents a half dollar profit. The traditional way to write division problems is with a division bracket.

Another method of writing division calculations is to use fractions. In a fraction, the top number, or numerator, is divided by the bottom number, or denominator. A fraction is a division problem at its heart. 1/2 is the same thing as 1÷2.

Many problems will ask you to turn division problems into fractions. A division problem such as 17÷8 is equal to 2 with a remainder of one. When it comes time to write the fraction, you will have a . Mathematics Glossary» Glossary Print this page.

Addition and subtraction within 5, 10, 20, , or Addition or subtraction of two whole numbers with whole number answers, and with sum or minuend in the range , , , or , respectively. However, you do still write the fraction as part of the quotient (answer to your division problem). Also, you would check this division problem the same way as a normal division problem; multiply the quotient (23) by the divisor (6) and then add the remainder (1).
