tolong pakai caranya

6. 7 jam + 50 menit = (7×3600) + (50×60) = 25200 + 3000 = 28200 detik

7. 7380 detik = 7380 × 1/60 = 123 menit

8. 180 L/menit = 180 × 1000 = 180.000 mL/menit

9. 2 cm3 = 2 : 1000 = 0,002 dm3

10. (gambarnya terpotong)



Semoga membantu yaa:)

6. 7 jam + 50 menit = 7 kali 60 = 420 kali 60 =25200
50 kali 60 = 3000
25200 + 3000 = 28200
