    Calculating the Least Common Multiple

    9.1    Find the Least Common Multiple

        The left denominator is :       50

        The right denominator is :       25

          Number of times each prime factor

          appears in the factorization of:

    Prime

    Factor   Left

    Denominator   Right

    Denominator   L.C.M = Max

    {Left,Right}

    2 1 0 1

    5 2 2 2

    Product of all

    Prime Factors  50 25 50

        Least Common Multiple:

        50

    Calculating Multipliers :

    9.2    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 :

    9.3      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.      837

     ——————————————————  =   ———

           L.C.M             50

     R. Mult. • R. Num.      279 • 2

     ——————————————————  =   ———————

           L.C.M               50  

    Adding fractions that have a common denominator :

    9.4       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:

    837 – (279 • 2)     279

    ———————————————  =  ———

         50            50

    Equation at the end of step

    9

    :

     279    2883     81

    (——— +  ————) –  ——

     50      50      25

    STEP

    10

    :

    Adding fractions which have a common denominator

    10.1       Adding fractions which have a common denominator

    Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

    279 + 2883     1581

    ——————————  =  ————

       50          25

    Equation at the end of step

    10

    :

    1581    81

    ———— –  ——

    25     25

    STEP

    11

    :

    Adding fractions which have a common denominator

    11.1       Adding fractions which have a common denominator

    Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

    1581 – (81)     60

    ———————————  =  ——

       25          1

    Final result :

    60
