The math topic practiced in this document involves converting fractions of metric units to their respective names, at an introductory level. Each problem presents a fraction (e.g., 1/1000, 1/100, 1/10) and asks for the correct metric prefix (like milli, centi, deci) associated with that fraction. It's part of a broader unit on scientific notation units. This is a fundamental skill for understanding the metric system and applying scientific notation in various contexts.
