Put in order from smallest to largest 43 km,30 m, 720 hm

Question

how do you do these type of problems

Answer 1

Lets convert these measures in terms of powers of 10 so that the conversions are in meters.

 

43 km = 43 x 10³ m = 43000 m

 

30 m

 

720 hm = 720 x 10² m = 72000 m

 

 

So from least to greatest length, you have

 

30 m , 43 km , 720 hm
