Step  1  :

            24
 Simplify   ——
            5 

Equation at the end of step  1  :

   141    21     24
  (——— -  ——) -  ——
   10     10     5 

Step  2  :

            21
 Simplify   ——
            10

Equation at the end of step  2  :

   141    21     24
  (——— -  ——) -  ——
   10     10     5 

Step  3  :

            141
 Simplify   ———
            10 

Equation at the end of step  3  :

   141    21     24
  (——— -  ——) -  ——
   10     10     5 

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:

 141 - (21)     12
 ——————————  =  ——
     10         1 

Equation at the end of step  4  :

  12    24
  —— -  ——
  1     5 

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Subtracting a fraction from a whole

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

           12     12 • 5
     12 =  ——  =  ——————
           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 :

 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:

 12 • 5 - (24)     36
 —————————————  =  ——
       5           5 

Final result :

  36           
  —— = 7.20000
