Solution - Reducing fractions to their lowest terms

Step  1  :

            7
 Simplify   —
            9

Equation at the end of step  1  :

       7
  1 -  —
       9

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  9  as the denominator :

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

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 - (7)     2
 ———————  =  —
    9        9

Final result :

  2           
  — = 0.22222 
  9
