  1. C = 15/19 . 27/33 + 15/19 . 19/33 – 15/19 . 13/33
    C = 15/19 . ( 27/33 + 19/33 – 13/33 )
    C = 15/19 . 1
    C = 15/19
    Vậy , C = 15/19 .

  2. Giải đáp:
     15/19 
    Lời giải và giải thích chi tiết:
    C = 15/19. 27/33 + 15/19 . 19/33 – 15/19 . 13/33   
    = 15/19 . ( 27/33 + 19/33 -13/33)
    =15/19 . ( 33/33)
    = 15/19 . 1  
    = 15/19 
    Vậy C = 15/19
