Solution - Reducing fractions to their lowest terms

Step  1  :

             3
 Simplify   ——
            -2

Equation at the end of step  1  :

         3
  -4 -  ——
        -2

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  -2  as the denominator :

           -4     -4 • -2
     -4 =  ——  =  ———————
           1        -2   

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:

 -4 • 2 - (3 • -1)     -5
 —————————————————  =  ——
         2             2 

Final result :

  -5            
  —— = -2.50000
