Rewriting the whole as an Equivalent Fraction

6.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

                       32x(-727379968)      32x(-727379968) • 10

    32x(-727379968) =  ———————————————  =  ————————————————————

                              1                     10        

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

6.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

32x(-727379968) • 10 - (81x1215752192)      90x(-727379968) - 81x1215752192

——————————————————————————————————————  =  ———————————————————————————————

                  10                                     10

Pulling out like terms :

7.1     Pull out like factors :

  90x(-727379968) - 81x1215752192  =   -9x(-727379968) • (9x1943132160 - 10)

Trying to factor as a Difference of Squares:

7.2      Factoring:  9x1943132160 - 10

Check :  9  is not a cube !!

Ruling : Binomial can not be factored as the difference of two perfect cubes

Final result :

 -9x(-727379968) • (9x1943132160 - 10)

                  10
