What is the metric equivalent of 10 decimeters in meters?

• A. 0.1 m
• B. 1 m
• C. 10 m
• D. 100 m

Answer: (B)

To determine the metric equivalent of 10 decimeters in meters, it's essential to know the relationship between decimeters and meters. One decimeter is equal to 0.1 meters. This means that to convert decimeters to meters, you multiply the number of decimeters by 0.1.

In this case, you have 10 decimeters. Therefore, the conversion to meters can be calculated as follows:

10 decimeters × 0.1 meters/decimeter = 1 meter.

This calculation shows that 10 decimeters is indeed equal to 1 meter, making it the correct answer. Understanding metric conversions is crucial since they often involve straightforward multiplication or division based on the metric system's prefixes, which indicate the scale of units. In this instance, recognizing that decimeters are a fraction (1/10) of a meter allowed for an easy transformation of the measurement.
