Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "0.7" was replaced by "(7/10)". 2 more similar replacement(s)

Step  1  :

             7
 Simplify   ——
            10

Equation at the end of step  1  :

   71     7     
  (—— -  ——) -  2
   10    10     

Step  2  :

            71
 Simplify   ——
            10

Equation at the end of step  2  :

   71     7     
  (—— -  ——) -  2
   10    10     

Step  3  :

Adding fractions which have a common denominator :

 3.1       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:

 71 - (7)     32
 ————————  =  ——
    10        5 

Equation at the end of step  3  :

  32    
  —— -  2
  5     

Step  4  :

Rewriting the whole as an Equivalent Fraction :

 4.1   Subtracting a whole from a fraction

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

         2     2 • 5
    2 =  —  =  —————
         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 :

 4.2       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:

 32 - (2 • 5)     22
 ————————————  =  ——
      5           5 

Final result :

  22           
  —— = 4.40000
