The metric system is used to measure length, distance, and other quantities. It is based on multiples of 10, which makes converting between units simple. Understanding the relationship between centimeters and decimeters helps students solve basic measurement questions.
1 Decimeter: Question
Question: How many decimeters are in a centimeter?
Options
| A. 10 decimeters | B. 1 decimeter |
| C. 0.1 decimeter | D. 100 decimeters |
Correct Answer
Option C: 0.1 decimeter
One centimeter is equal to 0.1 decimeter, or one-tenth of a decimeter.
Explanation: Conversion of Metric Units
The metric system uses prefixes to show the relationship between different units of measurement.
- Deci- means one-tenth (1/10).
- Centi- means one-hundredth (1/100).
One decimeter is equal to 10 centimeters.
Therefore:
1 decimeter = 10 centimeters
To convert centimeters into decimeters, divide the number of centimeters by 10.
For example:
1 cm ÷ 10 = 0.1 dm
Similarly, 5 centimeters equal 0.5 decimeters, and 20 centimeters equal 2 decimeters.
Final Answer
There are 0.1 decimeters in 1 centimeter.
Remember that 1 decimeter equals 10 centimeters. So, to convert centimeters into decimeters, simply divide the number of centimeters by 10.
