Solution - Reducing fractions to their lowest terms

Step  1  :

             1
 Simplify   ——
            20

Equation at the end of step  1  :

        1
  1 +  ——
       20

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  20  as the denominator :

          1     1 • 20
     1 =  —  =  ——————
          1       20  

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:

 20 + 1     21
 ——————  =  ——
   20       20

Final result :

  21           
  —— = 1.05000 
  20
