Metric Conversions for TEAS 7

Correct Answer: B

Rationale: The correct answer is B: 0.1 cm. 1 millimeter is equal to 0.1 centimeters because there are 10 millimeters in 1 centimeter. To convert millimeters to centimeters, you divide by 10. Choice A (1/100 cm) is incorrect because 1 millimeter is not equal to 1/100 of a centimeter. Choice C (1 cm) is incorrect because 1 millimeter is smaller than 1 centimeter. Choice D (10 cm) is incorrect because 1 millimeter is not equal to 10 centimeters; it is only 0.1 centimeters.

Correct Answer: A

Rationale: Certainly! To express 10^6 m in simpler terms, we need to convert meters to kilometers. 1 kilometer is equal to 1000 meters. Therefore, 10^6 m = 1,000,000 m = 1 km. Option A is correct because 1 kilometer is the equivalent of 10^6 meters. Options B, C, and D are incorrect because they represent larger units of measurement than meters. Megameter is 1,000,000 meters, gigameter is 1,000,000,000 meters, and terameter is 1,000,000,000,000 meters, making them larger than 10^6 meters.

Correct Answer: B
