# Fractions and Mixed Numbers

A fraction is a number expressed in the form of a part of a whole. A fraction is a number that is either a whole number or a non-whole number. For example, 1/2 and 3/4 are fractions. A mixed number is a number expressed in the form of a decimal number, with a non-whole number as a fraction. For example, 1.7 is a mixed number. The decimal system is the number system used in mathematics, physics, and engineering for representing and manipulating real numbers. Mathematical notation uses a variety of symbols and conventions to denote fractions and mixed numbers, including the use of superscripts, subscripts, and the fraction slash. The fraction slash is a fraction slash symbol used in mathematics to denote a fraction. Fractions are often indicated in the form of a fraction slash. The fraction slash is written between two numbers and represents the fractional part of the second number divided by the fractional part of the first number. The fraction slash can be used to form a mixed number from a fraction. The fraction slash is also used in currency, juxtaposed to the fractional part of a monetary amount such as a penny or a dollar. In mathematics, a number is a real number, which means that it can be expressed as a ratio of two integers, for example, 2.5. If a ratio can be expressed as an algebraic fraction, then it is a real number. For example, the ratio of 3 to 5 is the same as the fraction of 3 over 5 (written as 1/5), which is a real number. A real number can be thought of as a value on a number line, with the distances between each pair of real numbers representing a certain proportion of some quantity. A real number can be thought of as a point or a set of points on the number line. For example, the number 1 is the point at which the number line is divided into two equal parts: the first part to the left of the number 1 is the positive numbers, and the second part to the right of the number 1 is the negative numbers. Thus, the positive half of the number line is to the right of the number 1, and the negative half is to the left of the number 1. A real number is denoted by a decimal, exponential, or integer, followed by a period and then by a decimal or exponential. The decimal or exponential can be followed by an E or another letter, which is a superscript. The superscripts are used to denote the number of decimal places or the exponent, respectively. The rules for writing real numbers are as follows: The exponential of a given number a is written a" and the exponential of the exponential of a number a is written a". The fraction of a number is just a number, which can be a decimal, an exponential, or a rational number. The decimal can be followed by a period and then by a digit or an E. The digit or E can be followed by a period and then by a decimal. The fraction slash can be used to form a mixed number from a fraction.
