Question

18 9/11+8 11/14+2 12/11+15 3/14

Answer 1

Answer: 8109/77 in decimal form 105.31169

Step-by-step explanation: simplify 153/4

189 811  212  153

 ((———+———)+———)+———

Simplify   ———

           11

Find the Least Common Multiple

     The left denominator is :       11  

     The right denominator is :       14  

       Number of times each prime factor

       appears in the factorization of:

Prime  

Factor   Left  

Denominator   Right  

Denominator   L.C.M = Max  

{Left,Right}  

11 1 0 1

2 0 1 1

7 0 1 1

Product of all  

Prime Factors  11 14 154

Least Common Multiple:

     154

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 = 14

  Right_M = L.C.M / R_Deno = 11

Rewrite the two fractions into equivalent fractions

  L. Mult. • L. Num.      14535

  ——————————————————  =   —————

        L.C.M              154  

  R. Mult. • R. Num.      153 • 11

  ——————————————————  =   ————————

        L.C.M               154    

Adding fractions that have a common denominator :

7.4       Adding up the two equivalent fractions

14535 + 153 • 11     8109
