Penjelasan dengan langkah-langkah:

6. 2 minggu = 14 hari

14/3 × 60

= 280

..

8. 6/1,5 × 108

= 432

..

9. 72 orang = 132 hari

96 = x hari

..

x/72 = 132/96

x = 72 × 132/96

x = 99 hari

..

10. x/42 = 24/36

x = 42 × 24/36

x = 28

28 - 24 = tambahan 4 orang

11. x/20 = 15/25

x = 20 × 15/25

x = 12 hari

..

13. x/72 = 80/60

x = 72 × 80/60

x = 96 km/jam

..

14. 30 ÷ (1/30 + 1/20)

= 30 ÷ (2/60 + 3/60)

= 30 ÷ 5/60

= 60/60 ÷ 5/60

= 60 ÷ 5

= 12 hari

..

15. 7,5 km = 750.000 cm

750.000/5

= 1 : 15.000

..

16. 500 m = 50.000 cm

50.000 × 1 : 10.000

= 5 cm
