Situation: Which one of the following is not equal to 100 meters?

We were given 4 different choices with corresponding values, not let's start finding the correct answer.

=> 0.100 kilometers

1 meter = 0.001 km

100 meters = 0.1 km

=> 10 hectometers

1 meter = 0.01 hm

100 meters = 1 hm

=> 10,000 centimeters

1 meter = 100 centimeters

100 meters = 10 000 cm

=> 100,000 millimeters

1 meter = 1000 mm

100 meters = 100 000 mm

thus the not equal answer is hectometer
