Answer 1

Jawaban:

Penyelesaian :

9. 30 hari/x = 10 + 5 orang/10 orang

30 hari/x = 15 orang/10 orang

15 × x = 30 × 10

15x = 300

x = 300/15

x = 20 hari (b)

10. 16 kambing/16 + 8 kambing = x/3 hari

16 kambing/24 kambing = x/3 hari

24 × x = 16 × 3

24x = 48

x = 48/24

x = 2 hari (a)

Kesimpulan :

• Jawaban no 9. b. 20 hari
• Jawaban no 10. a. 2 hari
