  1. 36 over 31
  2. 31 over 36
  3. 71 over 36
  4. 36 over 71

hintHint:

Solving using the BODMASS rule.

The correct answer is: 71 over 36


    STEP BY STEP SOLUTION
    straight x space plus space open parentheses fraction numerator negative 8 over denominator 9 end fraction close parentheses space equals space 13 over 4 space cross times space 1 third
S o l v i n g space f o r space t h e space v a l u e space o f space x
straight x space equals space 13 over 4 space cross times space 1 third space plus space 8 over 9
F o l l o w i n g space t h e space B O D M A S S space r u l e space 1 s t space m u l t i p l y i n g space
equals space 13 over 12 space plus space 8 over 9
T a k i n g space L C M space o f space 12 space & space 9 space left parenthesis i. e space 36 right parenthesis
equals space fraction numerator 39 space plus space 32 over denominator 36 end fraction
equals space 71 over 36
