Solution - Reducing fractions to their lowest terms

Step  1  :

            2
 Simplify   —
            5

Equation at the end of step  1  :

        2
  7x -  —
        5

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

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

           7x     7x • 5
     7x =  ——  =  ——————
           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 :

 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:

 7x • 5 - (2)     35x - 2
 ————————————  =  ———————
      5              5   

Final result :

  35x - 2
  ———————
     5
