= 0,9 : 1000 / 1000.0000
= 9 x 10^-4/ 10^6
= 9 x 10^-4 x 10^6
= 9 x 10^2
= 900 kg/m3
3. 60 m/s = km/jam
= 60 : 1000 / 3600
= 0,06 / 3600
= 6 x 10^-2 / 3600
= 1 x 10^-2 x 10^2
= 1 km/jam
4. 5 km/jam = m/s
= 5 x 1000 / 3600
= 5000/3600
= 1,389 m/s
5. 1000 kg/m3 = gr/cm3
= 1000 x 1000 / 1000.000
= 1 gr/ cm3
0,9 gr/cm³ = (0,9 x 10⁶) / 10³
= 0,9 x 10³
= 900 kg/m³
nomor 3 :
60 m/s = (60x3.600)/1000
= 216.000/1000
= 216 km/jam
nomor 4 :
5 km/jam = (5x1000)/3.600
= 1,3889 m/s
nomor 5 :
1000 kg / m³= (1000x1000)/10⁶
= 10⁶/10⁶
= 1 g/cm³
