jawab no 9 - 12 #Kalau Asal asalan D o s a

9. 3/6 + 1/4
= 12/24 + 6/24
= 18/24
= 3/4 (D)

10. 2/3 + 1/4 + 1/2
= 8/12 + 3/12 + 6/12
= 11/12 + 6/12
= 17/12 (C)

11. 5/9 - 1/3
= 5/9 - 3/9
= 2/9 (C)

12. 3/10 + 3/4
= 6/20 + 15/20
= 21/20 (B)

9. 3/6+1/4= 12+6/24=18/24= 9/12
10. 2/3+1/4+1/2= 8+3+6/12=17/12 (c)
11. 5/9-1/3= 5-3/9= 2/9 (c)
12. 3/10+3/4= 12+30/40=42/40=1 2/40= 1 1/20
