Final answer:
The correct answer Metric to Metric conversion (a). Metric prefixes indicate powers of ten, allowing for easy conversion between different metric units by simply moving the decimal point.
Step-by-step explanation:
The correct answer is option a. Metric to Metric. When converting measures within the metric system, we use prefixes like kilo-, hecto-, deca-, deci-, centi-, and milli-.
These metric prefixes are based on powers of ten and are used worldwide in the scientific community due to their simplicity and universal standardization. For instance, if you have a measurement in centimeters and want to convert it to meters, you move the decimal place accordingly because there are 100 centimeters in a meter.
The use of metric prefixes such as K (kilo-), H (hecto-), D (deca-), U (unit—no prefix), D (deci-), C (centi-), and M (milli-) makes it straightforward to scale values up or down by powers of ten, facilitating easy conversions within the metric system itself.
