Jawaban yang tepat adalah -5

 

Pembahasan :

323/5 + 811/4 - 642/3 = (25)3/5 + (34)1/4 - (26)2/3 

                                       = 23 + 3 - 24

                                       = 8 + 3 - 16

                                       = 11 - 16

                                       = -5
