            Converting Decimals into Fractions

            Rules of converting decimal number into fraction are :

            «  Write the given number leaving out the decimal point in the numerator.

            « Write 1 in the denominator followed by as many zeros as the decimal places.

            « Then, write the resulting fraction in the lowest form.

            Example  :  Convert 1.5 into fraction.

            Solution  :  Given decimal number is 1.5.

                          To  convert  1.5  into  fractional  number,  first  we  need  to  write  15  in  the
                           numerator  leaving  out  of  the  decimal  point  and  then  write  10  in  the
                           denominator since after the decimal point there is one number.

                                     15
                                   =

                                             15
                          Now, simplify        to its lowest form.
