Question

what is a major advantage in using the metric system? choose the correct answer below. a. the metric system gives its answers as mixed numbers with fractions. b. the metric system uses powers of 10 to define units, so the arithmetic to change from one unit to another is relatively simple. c. the metric system uses kilometers as the basic measurement. d. the metric system uses powers of 2 to define units, so the arithmetic to change units is relatively simple.

Explanation:

The metric system is based on powers of 10. This makes unit - conversion arithmetic straightforward. For example, to convert from meters to centimeters, you multiply by 100 (since 1 m = 100 cm) as 100 is a power of 10 ($10^2$). It doesn't use powers of 2 for unit - definition and doesn't give answers as mixed numbers with fractions as a major advantage. Also, the basic unit of length is the meter, not the kilometer.

Answer:

B. The metric system uses powers of 10 to define units, so the arithmetic to change from one unit to another is relatively simple.
