Metric Conversions for TEAS 7

Correct Answer: A

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.

Correct Answer: C

Rationale: To convert a decimal to inches, we know that 1 inch is equal to 1.0. So, 0.13 inches can be written as 0.13 * 1 inch which equals 0.13 inches. A: 0.013 inches - Incorrect, this is a smaller value than 0.13 inches. B: 1.3 inches - Incorrect, this is a larger value than 0.13 inches. D: 13 inches - Incorrect, this is a significantly larger value than 0.13 inches. Therefore, the correct answer is C as 0.13 inches is the equivalent decimal value.

Correct Answer: B

Rationale: The correct answer is B: 100 cm. There are 100 centimeters in 1 meter because the metric system is based on units of 10. 1 meter is equivalent to 100 centimeters as each meter is divided into 100 equal parts, which are centimeters. Choice A (10 cm) is incorrect as it represents the number of millimeters in a centimeter. Choice C (1,000 cm) is incorrect as it represents the number of millimeters in a meter. Choice D (10,000 cm) is incorrect as it is ten times the actual number of centimeters in a meter.

Correct Answer: D

Rationale: The correct answer is D: 1000 milliliters. 1 liter is equivalent to 1000 milliliters. This is because the metric system is based on the powers of 10, so there are 1000 milliliters in 1 liter. Choice A, 1 kilogram, is a unit of mass and not volume. Choice B, 1 quart, is a unit of volume but is not equivalent to 1 liter. Choice C, 1 milliliter, is much smaller than 1 liter, as it would take 1000 milliliters to make up 1 liter.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 0.75 kg * 1000 = 750 grams. Therefore, choice B (750 grams) is correct. Choice A (75 grams) is incorrect as it is a decimal point off; choice C (7,500 grams) is incorrect as it is off by a factor of 10; and choice D (75,000 grams) is incorrect as it is off by a factor of 100.
