Chapter 2, Problem 62A

Interpretation Introduction

Interpretation:

The number of meters in one kilometer and in one decimeter needs to be determined.

Concept introduction:

Metric system is defined as a system of measurements that uses the liter, meter, and gram as base units of capacity (volume), length (distance), and weight (mass) respectively.

Answer to Problem 62A

There are $\text{1000}\text{meters}$ in one kilometer and $\text{0}\text{.1}\text{meters}$ in one decimeter.

Explanation of Solution

Prefixes are very important as they give the magnitude for a particular number. Prefixes also allow the large numbers to be written in the form of smaller units.

Here, $\text{1000}\text{meters}$ is equal to $\text{1}\text{kilometer}$ because the prefix ‘‘kilo’’ represents $1000$. There are $\text{0}\text{.1}\text{meters}$ in one decimeter because the prefix ‘‘deci’’ indicates one tenth $\left(\frac{1}{10}\right)$.

Conclusion

Thus, there are $\text{1000}\text{meters}$ in one kilometer and $\text{0}\text{.1}\text{meters}$ in one decimeter.
