A deciliter (dL) is how much of a liter?

  1. 1/5 of a liter

  2. 1/10 of a liter

  3. 1/50 of a liter

  4. 1/100 of a liter

The correct answer is: 1/10 of a liter

A deciliter (dL) represents one-tenth of a liter. The metric system is based on powers of ten, and within this system, one liter is divided into ten equal parts, each of which is defined as a deciliter. Therefore, stating that a deciliter is 1/10 of a liter is accurate because it aligns with the fundamental metric system structure, where each prefix signifies a specific fraction of the base unit. In this case, "deci-" indicates a division by ten, clearly establishing that a deciliter is indeed one-tenth of a liter.
