Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "b9"   was replaced by   "b^9". 

Step  1  :

             v 
 Simplify   ———
            210

Equation at the end of step  1  :

            v           
  ((6000 • ———) • t) -  b935
           210          

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  7  as the denominator :

            b935      b935 • 7 
    b935 =  ————  =  ————————
             1          7    

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 :

 2.2       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:

 200vt - (b935 • 7)      200vt - 7b935 
 ——————————————————  =  —————————————
         7                    7      

Final result :

  200vt - 7b935 
  —————————————
        7
