Solution - Adding, subtracting and finding the least common multiple

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "1.3" was replaced by "(13/10)". 2 more similar replacement(s)

Step  1  :

            13
 Simplify   ——
            10

Equation at the end of step  1  :

   149    13     
  (——— -  ——) -  4
   10     10     

Step  2  :

            149
 Simplify   ———
            10 

Equation at the end of step  2  :

   149    13     
  (——— -  ——) -  4
   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:

 149 - (13)     68
 ——————————  =  ——
     10         5 

Equation at the end of step  3  :

  68    
  —— -  4
  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 :

         4     4 • 5
    4 =  —  =  —————
         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:

 68 - (4 • 5)     48
 ————————————  =  ——
      5           5 

Final result :

  48           
  —— = 9.60000
