jwb y no 11-12 memakai cara

11. 3 1/3 = 10/3
      2/4 = 1/2
      maka, 10/3 : 1/2 = 10/3 x 2 = 20/3 = 6 2/3  (B)

12. 238% = 238/100 = 2 38/100
      2 38/100 masih bisa disederhakan menjadi 2 19/50  (C)

semoga membantu :)

11. 3 1/3 : 2/4 = 10/3 : 2/4
= 10/3 × 4/2
= 40/6
jadi, 6 4/6 = 6 2/3
Jawab = B

12. 238% = 238/100
= 2 38/100
= 2 19/50
Jawab = C
