Praxis 5003 Practice Question
An eraser weighs 20 grams. Which of the following represents the weight of the eraser in milligrams?
Correct Answer: D
Rationale: To convert grams to milligrams, multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 20 grams equals 20,000 milligrams.
Option A (1.002) is incorrect as it misrepresents the conversion entirely. Option B (0.02) is also incorrect; it suggests a significant underestimation of the weight. Option C (2,000) is wrong because it mistakenly divides the weight by 10 instead of correctly multiplying.
Option D accurately reflects the weight of the eraser in milligrams, confirming that 20 grams is equivalent to 20,000 milligrams.
