Solution - Adding, subtracting and finding the least common multiple

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                     b-3/4-(1/2)<0 

Step by step solution :

Step  1  :

            1
 Simplify   —
            2

Equation at the end of step  1  :

        3     1
  (b -  —) -  —  < 0 
        4     2

Step  2  :

            3
 Simplify   —
            4

Equation at the end of step  2  :

        3     1
  (b -  —) -  —  < 0 
        4     2

Step  3  :

Rewriting the whole as an Equivalent Fraction :

 3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  4  as the denominator :

          b     b • 4
     b =  —  =  —————
          1       4  

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 :

 3.2       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:

 b • 4 - (3)     4b - 3
 ———————————  =  ——————
      4            4   

Equation at the end of step  3  :

  (4b - 3)    1
  ———————— -  —  < 0 
     4        2

Step  4  :

Calculating the Least Common Multiple :

 4.1    Find the Least Common Multiple

      The left denominator is :       4 

      The right denominator is :       2 

      Least Common Multiple:
      4 

Calculating Multipliers :

 4.2    Calculate multipliers for the two fractions


    Denote the Least Common Multiple by  L.C.M 
    Denote the Left Multiplier by  Left_M 
    Denote the Right Multiplier by  Right_M 
    Denote the Left Deniminator by  L_Deno 
    Denote the Right Multiplier by  R_Deno 

   Left_M = L.C.M / L_Deno = 1

   Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

 4.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)²   and  (y²+y)/(y+1)³  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

   L. Mult. • L. Num.      (4b-3)
   ——————————————————  =   ——————
         L.C.M               4   

   R. Mult. • R. Num.      2
   ——————————————————  =   —
         L.C.M             4

Adding fractions that have a common denominator :

 4.4       Adding up the two equivalent fractions

 (4b-3) - (2)     4b - 5
 ————————————  =  ——————
      4             4   

Equation at the end of step  4  :

  4b - 5
  ——————  < 0 
    4   

Step  5  :

 5.1    Multiply both sides by  4 

 5.2    Divide both sides by  4  

      b-(5/4)  < 0

Solve Basic Inequality :

 5.3      Add  5/4  to both sides

             b < 5/4
