Within the metric system, all units are based on the number
A) 10.
B) 1.
C) 1,000.
D) 100.
Answer (2)
The metric system is based on scaling units by powers of a number.
The metric system uses powers of 10 for scaling.
Therefore, the base number of the metric system is 10.
The answer is 10 .
Explanation
Understanding the Question The question asks us to identify the base number upon which the metric system is built. We need to consider the fundamental principle of the metric system, which involves scaling units by powers of a certain number.
The Base of the Metric System The metric system is designed around powers of 10. This means that units increase or decrease in size by factors of 10. For example, a kilometer is 1000 meters, a centimeter is 1/100 of a meter, and so on.
Identifying the Correct Option Based on the above, the correct answer is A) 10.
Examples
Imagine you're measuring ingredients for a recipe. The metric system, based on the number 10, makes it easy to scale recipes up or down. If a recipe calls for 200 grams of flour and you want to double it, you simply multiply by 2 to get 400 grams. This simple multiplication is possible because the metric system uses powers of 10, making conversions and scaling straightforward in everyday situations like cooking, construction, and science.
The metric system is fundamentally based on the number 10, as it uses powers of 10 for scaling units. This structure simplifies conversions within the system. Hence, the correct answer is A) 10.
