7km is 350000 times greater than 2cm.
Solution:
1. Clarify the question "How many times greater is 7km than 2cm?"
2. Convert both units into meters: 7*1000=7000m, 2*1/100=.02m
3. Divide the big number by the small number: 7000 / .02 = 350000

Answer 1:
100 cm in a m, 1000 m in a km. 3.5 2 in 7. 3.5 * 100*1000 = 350000
centi-meters = 10**-2 meters
kilo-meteres = 10**3 meters
2cm < 7km
2*10**-2/7*10**3 = (2/7)*10**-5

The second one.
yes almost 5 times greater 139 cm/sec x 60sec/min = 18,340 cm/min x 60min/hour = 1,100,400 cm/hour /100,000 cm/km = 11.004 km/hour
10 km is greater.
By knowing that centi means 100th part and kilo means 1000 times. So there must be 100,000 cm in 1 km.
