Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): ".625" was replaced by "(625/1000)".

Step  1  :

            5
 Simplify   —
            8

Equation at the end of step  1  :

       5     
  (r • —) -  1
       8     

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

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

         1     1 • 8
    1 =  —  =  —————
         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:

 5r - (8)     5r - 8
 ————————  =  ——————
    8           8   

Final result :

  5r - 8
  ——————
    8
