What is the metric equivalent of one decimeter?

1. 1/100 meter

2. 1/10 meter

3. 1 meter

4. 1000 meters

The correct answer is: 1/100 meter

One decimeter is defined as one-tenth of a meter, making it equivalent to 1/10 meter. The metric system is based on powers of ten, which allows for straightforward conversion between units. Specifically, there are ten decimeters in one meter, demonstrating that each decimeter is significantly smaller than a full meter but is a practical unit for measuring length in contexts where smaller measures are more appropriate. In context, since the question asks about the metric equivalent of a decimeter, the correct choice provides the precise conversion as a fraction of a meter. Other options refer to alternative measures within the metric system, but they either represent different unit scales or incorrect fractions relating to a decimeter. Understanding the relationships between these units is crucial for anyone engaging with the metric system.
