Solution - Adding, subtracting and finding the least common multiple

Step  1  :

            1
 Simplify   —
            4

Equation at the end of step  1  :

         5     3     1
  ((0 -  —) -  —) -  —
         8     8     4

Step  2  :

            3
 Simplify   —
            8

Equation at the end of step  2  :

         5     3     1
  ((0 -  —) -  —) -  —
         8     8     4

Step  3  :

            5
 Simplify   —
            8

Equation at the end of step  3  :

         5     3     1
  ((0 -  —) -  —) -  —
         8     8     4

Step  4  :

Adding fractions which have a common denominator :

 4.1       Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 -5 - (3)     -1
 ————————  =  ——
    8         1 

Equation at the end of step  4  :

  -1    1
  —— -  —
  1     4

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  4  as the denominator :

           -1     -1 • 4
     -1 =  ——  =  ——————
           1        4   

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 :

 5.2       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:

 -1 • 4 - (1)     -5
 ————————————  =  ——
      4           4 

Final result :

  -5            
  —— = -1.25000
