Final answer:
In the metric system, 1 decimeter (dm) is equal to 0.1 meter (m). The prefix 'deci' represents one-tenth, making a decimeter one-tenth of a meter.
Step-by-step explanation:
In measurement units, 1 decimeter (dm) equals to 0.1 meter (m). This is because the prefix 'deci' stands for one-tenth, so a decimeter is one-tenth of a meter. Therefore, we can say in the metric system, there are 10 decimeters in a meter. To convert 1 dm to meters, you would divide by 10 because there are 10 decimeters per meter, resulting in 0.1 meters.
