Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "1.55" was replaced by "(155/100)".

Step  1  :

            31
 Simplify   ——
            20

Equation at the end of step  1  :

       31
  4 -  ——
       20

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

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

          4     4 • 20
     4 =  —  =  ——————
          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:

 4 • 20 - (31)     49
 —————————————  =  ——
      20           20

Final result :

  49           
  —— = 2.45000 
  20
