Metric Conversions for TEAS 7

Correct Answer: B

Rationale: To convert milligrams to grams, you need to divide by 1000 since there are 1000 milligrams in 1 gram. Therefore, 35,400 mg divided by 1000 equals 35.4 grams. Choice B, 35.4 g, is the correct answer as it correctly represents the conversion. Choices A, C, and D are incorrect because they do not perform the correct conversion calculation. Choice A incorrectly moves the decimal point, choice C multiplies instead of divides, and choice D adds an extra zero.

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: D

Rationale: To convert 0.075 mg to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. So, 0.075 mg * 1000 = 75 mcg. Therefore, the correct answer is D: 750 mcg. Choices A, B, and C are incorrect as they do not correctly convert milligrams to micrograms.

Correct Answer: A

Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in 1 kilogram. Therefore, 34.5 grams divided by 1000 equals 0.0345 kilograms or 3.45 kg (A). The other choices are incorrect because B is the original value in kg, C is 100 times the value in kg, and D is the original value in grams.

Correct Answer: C

Rationale: To convert kilograms to grams, we need to multiply the number of kilograms by 1000 since there are 1000 grams in 1 kilogram. Therefore, to find out how many grams are in 5 kilograms, we multiply 5 by 1000, which equals 5000 grams. The correct answer is C. A: 50 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 50 grams. B: 500 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 500 grams. D: 5 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 5 grams.
