Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.4" was replaced by "(4/10)".

Step  1  :

            2
 Simplify   —
            5

Equation at the end of step  1  :

              2
  0 -  (77 +  —)
              5

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  5  as the denominator :

           77     77 • 5
     77 =  ——  =  ——————
           1        5   

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:

 77 • 5 + 2     387
 ——————————  =  ———
     5           5 

Equation at the end of step  2  :

       387
  0 -  ———
        5 

Step  3  :

Final result :

  -387             
  ———— = -77.40000
