Jawaban:
6. C. 12
7. A. 16.000
8. C. 7
9. B. 4 : 7
10. A. 3 : 10
11. B. 1 : 3
12. C. 4/3
Penjelasan dengan langkah-langkah:
[tex]6. \: a - 15 = - 3 \\ a = - 3 + 15 \\ a = 12[/tex]
[tex]7. \: 6 \: kg = 100.000 - 4.000 \\ 6 \: kg = 96.000 \\ 1 \: kg = \frac{96.000}{6} \\ 1 \: kg = 16.000[/tex]
[tex]8. \: (120 - 8) \div 16 = 112 \div 16 \\ = 7[/tex]
9. sebelum = 40
sesudah = 40 + 30 = 70
sebelum : sesudah = 40 : 70 = 4 : 7
10. dina = 12
seluruh kerang = 18 + 12 + 10 = 40
kerang dina : seluruh kerang = 12 : 40 = 3 : 10
11. Ari = 700 m
Ira = 2,1 km = 2.100 m
Ari : Ira = 700 : 2.100 = 1 : 3
12. Vina = 80
Nurul = 60
[tex]\frac{vina}{nurul} = \frac{80}{60} = \frac{8}{6} = \frac{4}{3} [/tex]
