Solution - Reducing fractions to their lowest terms

Step  1  :

            3
 Simplify   —
            8

Equation at the end of step  1  :

            3
  9 -  (7 • —)
            8

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  8  as the denominator :

          9     9 • 8
     9 =  —  =  —————
          1       8  

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 :

 2.2       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:

 9 • 8 - (21)     51
 ————————————  =  ——
      8           8 

Final result :

  51           
  —— = 6.37500 
  8
