Metric Conversions for TEAS 7

Correct Answer: C

Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.

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: C

Rationale: The correct answer is C: 1,000 grams. There are 1,000 grams in 1 kilogram because the prefix "kilo-" in the metric system signifies 1,000. Therefore, 1 kilogram equals 1,000 grams. Choice A (10 grams) is incorrect because it is not equivalent to a kilogram. Choice B (100 grams) is incorrect as well, as it is also not the correct conversion. Choice D (10,000 grams) is incorrect because it is ten times the amount in a kilogram.

Correct Answer: B

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter equals 1000 milliliters. Therefore, 0.09 liters x 1000 = 90 milliliters. The correct answer is B. Choice A is incorrect as it does not convert liters to milliliters. Choice C is incorrect as it is 10 times the correct answer. Choice D is incorrect as it is 1/10 of the correct answer.

Correct Answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.1 * 1000 = 100 ml, which is the correct answer (B). Choice A (10 ml) is incorrect as it represents 0.01 liters, choice C (1000 ml) is incorrect as it represents 1 liter, and choice D (1 ml) is incorrect as it is too small for 0.1 liters.
