Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is 0.875 converted to a fraction?
Correct Answer: A
Rationale: To convert 0.875 to a fraction, note that it is equivalent to 875/1000. Simplifying by dividing both numerator and denominator by 125 gives 7/8. This is the correct answer because it is the simplest form of the fraction. Choice B (8/7) is incorrect as it represents a fraction greater than 1. Choice C (3/4) is incorrect as it is not equivalent to 0.875. Choice D (9/10) is incorrect as it does not match the decimal value of 0.875.
Question 2 of 5
What is the metric equivalent of 1 inch?
Correct Answer: B
Rationale: The correct answer is B: 2.54 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. This conversion factor is based on the definition of an inch and a centimeter. Therefore, 1 inch is equivalent to 2.54 centimeters. Choice A (1.54 cm) is incorrect as it is not the correct conversion factor for inches to centimeters. Choice C (3.54 cm) and Choice D (4.54 cm) are also incorrect as they do not correspond to the accurate conversion of inches to centimeters.
Question 3 of 5
How many centimeters are in 1 meter?
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.
Question 4 of 5
What is 0.25 mg to mcg?
Correct Answer: A
Rationale: To convert mg to mcg, we need to multiply by 1000 since 1 mg = 1000 mcg. So, 0.25 mg x 1000 = 250 mcg. Therefore, the correct answer is A: 250 mcg. Choice B, C, and D are incorrect because they do not correctly convert milligrams to micrograms.
Question 5 of 5
What does 'kg' stand for in the metric system?
Correct Answer: A
Rationale: The correct answer is A: kilogram. In the metric system, 'kg' stands for kilogram, which is the unit of mass. The prefix 'kilo-' denotes 1000, so a kilogram is equal to 1000 grams. This is the standard unit used to measure mass in the metric system. B: keg is incorrect as it is a container for storing liquids, not a unit of measurement. C: kroner is the currency used in Norway and Denmark, not a unit of measurement in the metric system. D: kraken is a mythical sea monster and not related to any unit of measurement. Therefore, the correct choice is A as it corresponds to the standard unit for mass in the metric system.
