          Fractions

Definition: - The numbers which can be expressed  

                    In the form of p/q form where P and   are                                                 Natural Numbers like 2/3, 5/7 are called            

                     Fractions.

Some Learning Points:-

Lowest term: - If in a fraction there are no common factor is called

                        Lowest term.

                        In a p/q form pi called as Numerator and q is called as                             Denominator.

Standard form:- in standard form like as we write 4/-8 it is fraction but

                          Not in standard form its standard form is -4/8.

Method to convert a number into Standard form.

1.   We have 4/-8.

2.     Multiply Number & Denominator with -1.

3.     We get -4/8 which is in Standard Form.

Equivalent:-

1.   Here some fractions are Equal.

2.   Like as 2/5 and 4/10 are Equal.

Types of Fraction:-

1.   Proper Fraction:-The fraction in which denominator is greater

                               Than Numerator. Like 2/3.

2.    Improper Fraction:- The fraction in which Denominator is smaller

                                 Than Numerator. Like 5/4.

                                                         

3.   Mixed Fraction:- when we have a Improper Fraction then we

                           Divided Numerator by denominator and write

                           12 ½. We multiply Denominator with 12 and add 1.
