Minta tolong cara dan jawaban dari:
1. 5 1/3 +2 1/7 +5 2/5 : 1 1/2=

2. 1 3/5 x 2 1/4 - 1 2/7 + 4 1/2=

Answer 1

1. 5 1/3 + 2 1/7 + 5 2/5 : 1 1/2
   = 16/3 + 15/7 + 27/5 : 3/2
   = 16/3 + 15/7 + 27/5 x 2/3
   = 16/3 + 15/7 + 54/15
   = 16/3 + 15/7 + 18/5
   = (560 + 225 + 378)/105
   = 1163/105
   = 11 8/105

2. 1 3/5 x 2 1/4 - 1 2/7 + 4 1/2
   = 8/5 x 9/4 - 9/7 + 9/2
   = 18/5 - 9/7 + 9/2
   = (252 - 90 + 315)/70
   = 477 / 70
   = 6 57/70

Semoga membantu :)
