Reformatting the input :

Changes made to your input should not affect the solution:

(1): "2.5" was replaced by "(25/10)". 2 more similar replacement(s)

Rearrange:

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

                     w-(18/10)-((25/10))<0 

Step by step solution :

Step  1  :

            5
 Simplify   —
            2

Equation at the end of step  1  :

        18     5
  (w -  ——) -  —  < 0 
        10     2

Step  2  :

            9
 Simplify   —
            5

Equation at the end of step  2  :

        9     5
  (w -  —) -  —  < 0 
        5     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  5  as the denominator :

          w     w • 5
     w =  —  =  —————
          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 :

 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:

 w • 5 - (9)     5w - 9
 ———————————  =  ——————
      5            5   

Equation at the end of step  3  :

  (5w - 9)    5
  ———————— -  —  < 0 
     5        2

Step  4  :

Calculating the Least Common Multiple :

 4.1    Find the Least Common Multiple

      The left denominator is :       5 

      The right denominator is :       2 

      Least Common Multiple:
      10 

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 = 2

   Right_M = L.C.M / R_Deno = 5

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.      (5w-9) • 2
   ——————————————————  =   ——————————
         L.C.M                 10    

   R. Mult. • R. Num.      5 • 5
   ——————————————————  =   —————
         L.C.M              10  

Adding fractions that have a common denominator :

 4.4       Adding up the two equivalent fractions

 (5w-9) • 2 - (5 • 5)     10w - 43
 ————————————————————  =  ————————
          10                 10   

Equation at the end of step  4  :

  10w - 43
  ————————  < 0 
     10   

Step  5  :

 5.1    Multiply both sides by  10 

 5.2    Divide both sides by  10  

      w-(43/10)  < 0

Solve Basic Inequality :

 5.3      Add  43/10  to both sides

             w < 43/10
