Fractions Lesson 1 SLIDESMANIA.C  What is a Fraction? Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing. SLIDESMANIA.C SLIDESMANIA.C  Parts of a Fraction All fractions consist of a numerator and a denominator, and they are separated by a horizontal bar known as the fractional bar. The denominator indicates the number of parts in which the whole has been divided into. It is placed in the lower part of the fraction below the fractional bar. The numerator indicates how many sections of the fraction are represented or selected. It is placed in the SLIDESMANIA.C upper part of the fraction above the fractional bar. SLIDESMANIA.C  Types of Fractions: * Vulgar * Proper * Improper * Mixed Number SLIDESMANIA.C  Vulgar Fraction A vulgar fraction, common fraction or fraction is a fraction written in the usual way which is one number (integer) above another (integer) separated by a line. SLIDESMANIA.C SLIDESMANIA.C  Proper Fraction Proper fractions are the fractions in which the numerator is less than its denominator. SLIDESMANIA.C  Improper Fraction An improper fraction is the type of fraction in which the numerator is more than or equal to its denominator. It is always the same or greater than the whole. SLIDESMANIA.C  Mixed Number/Fraction A mixed fraction is a mixture of a whole number and a proper fraction.
