Question

How many decimeters are there in one meter?

• A. 10 decimeters
• B. 40 decimeters
• C. 20 decimeters
• D. 50 decimeters

Hint:

Metric conversions: 1 meter = 10 decimeters, 1 decimeter = 10 centimeters, 1 meter = 100 centimeters.

Answer 1

The Correct Option is A

Defining a decimeter
Step 1: A decimeter is a metric unit of length equal to one
-tenth of a meter.
Converting to decimeters
Step 2: Since 1 meter = 10 decimeters (as \( 1 \, \text{m} = 10 \times 0.1 \, \text{m} \)).
Evaluating options
Step 3: Analyze the options:
- (A) 10 decimeters: Correct, as 1 meter = 10 decimeters.
- (B) 40 decimeters: Incorrect, as 40 dm = 4 meters.
- (C) 20 decimeters: Incorrect, as 20 dm = 2 meters.
- (D) 50 decimeters: Incorrect, as 50 dm = 5 meters.
Thus, the correct answer is (A).
