What is the correct conversion of 35,400 milligrams to grams (g)?

Correct Answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram. Therefore, 35,400 mg · 1,000 = 35.4 grams. Choice A is incorrect because it does not account for the conversion from milligrams to grams. Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion. Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.

Correct Answer: B

Rationale: The correct answer is B) France. The metric system was developed in France during the French Revolution in the late 18th century. The French Academy of Sciences played a significant role in creating the system of measurement that we now know as the metric system. This answer is correct because historically, France is recognized as the birthplace of the metric system. Option A) Germany is incorrect because the metric system did not originate in Germany. While Germany did adopt the metric system later on, it was not the country where it was developed. Option C) Italy is incorrect because Italy also did not play a role in the development of the metric system. Italy, like many other countries, eventually adopted the metric system, but it was not the country of origin. Option D) Spain is incorrect because Spain was not where the metric system was developed. Like other countries, Spain eventually adopted the metric system but did not have a hand in its creation. Understanding the historical context of the metric system's development is essential for students studying for the TEAS exam. Knowing the origins of the metric system helps students appreciate its significance and understand why it is used universally in scientific and mathematical fields today.

Correct Answer: B

Rationale: The prefix 'centi' means 0.01, which is one-hundredth of the base unit. For example, 1 centimeter is equal to 0.01 meters. Choice A (0.1) is incorrect as it represents 'deci,' which means one-tenth. Choice C (0.001) is incorrect as it represents 'milli,' which means one-thousandth. Choice D (1) is incorrect as it is not a valid interpretation of the prefix 'centi.' Therefore, the correct answer is B.

Correct Answer: B

Rationale: A balance scale is specifically designed to measure the mass of an object in grams or kilograms. It works based on the principle of balancing the unknown mass against a known mass. A thermometer is used to measure temperature, not mass, so choice A is incorrect. Choice C, 'scale,' is a bit vague and can refer to different types of scales, but a balance scale is the specific instrument used for measuring mass. Choice D, 'caliper,' is used for measuring dimensions such as length, width, or thickness, not mass.

Correct Answer: C

Rationale: In this question, the correct answer is C) 5000 grams. To understand why this is the right answer, we need to recall the metric system conversion factors. In the metric system, there are prefixes that indicate different magnitudes of the base unit. In this case, we are converting from kilograms to grams. 1 kilogram is equal to 1000 grams. Therefore, to convert kilograms to grams, we need to multiply the given value in kilograms by 1000. So, 5 kilograms x 1000 = 5000 grams. Now, let's analyze why the other options are incorrect: A) 50 grams: This answer is incorrect because it does not account for the conversion factor of 1000 between kilograms and grams. B) 500 grams: This answer is incorrect because it represents half of the correct conversion. It fails to apply the full conversion factor of 1000. D) 5 grams: This answer is incorrect as it fails to recognize the difference in magnitude between kilograms and grams. Educationally, understanding metric conversions is crucial for various fields such as science, healthcare, and engineering. It is essential for students to grasp these conversions to work accurately with measurements in real-world scenarios. By practicing and understanding these conversions, students can improve their quantitative reasoning skills and enhance their ability to work with measurements effectively.
