Step  1  :

            17
 Simplify   ——
            10

Equation at the end of step  1  :

   74     4     17
  (—— -  ——) -  ——
   10    10     10

Step  2  :

            2
 Simplify   —
            5

Equation at the end of step  2  :

   74    2     17
  (—— -  —) -  ——
   10    5     10

Step  3  :

            37
 Simplify   ——
            5 

Equation at the end of step  3  :

   37    2     17
  (—— -  —) -  ——
   5     5     10

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:

 37 - (2)     7
 ————————  =  —
    5         1

Equation at the end of step  4  :

  7    17
  — -  ——
  1    10

Step  5  :

Rewriting the whole as an Equivalent Fraction :

 5.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

          7     7 • 10
     7 =  —  =  ——————
          1       10  

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:

 7 • 10 - (17)     53
 —————————————  =  ——
      10           10

Final result :

  53           
  —— = 5.30000 
  10
