Question

Arrange the following from least to greatest: $6,700$ meters, $672,000$ centimeters, and $6.6$ kilometers.

Answer 1

For simplicity of comparison, let us convert every thing into meters
$672000$ centimeters is equivalent to $\frac{672000}{100}=6720$ meters
$6.6$ kilometers is equivalent to $6.6\times 1000=6600$ meters
Therefore, $6.6$ kilometers is $<$ $6700$ meters is $<$ $672000$ centimeters.
