Metric Conversions for TEAS 7 Questions
Question 1 of 5
What does the prefix 'centi' mean?
Correct Answer: B
Rationale: The prefix 'centi' denotes the factor of 0.01. This is because 'centi' comes from the Latin word 'centum' which means one hundred. Therefore, 'centi' represents 1/100 or 0.01. The correct answer is B (0.01). Choice A (0.1) is incorrect as 'centi' is smaller than that. Choice C (0.001) is incorrect as it represents 'milli', not 'centi'. Choice D (1) is incorrect as 'centi' denotes a fraction of one, not a whole unit.
Question 2 of 5
How many kilometers (km) is equivalent to 1,000 meters?
Correct Answer: B
Rationale: To convert meters to kilometers, we divide by 1,000 since 1 kilometer is equal to 1,000 meters. Therefore, 1,000 meters divided by 1,000 equals 1 kilometer. Hence, the correct answer is B: 1 km. A: 0.1 km - Incorrect. This would be the equivalent of 100 meters. C: 10 km - Incorrect. This would be the equivalent of 10,000 meters. D: 0.01 km - Incorrect. This would be the equivalent of 10 meters.
Question 3 of 5
Where was the metric system developed?
Correct Answer: B
Rationale: The correct answer is B: France. The metric system was developed in France during the French Revolution in the late 18th century. The French Academy of Sciences proposed the system to standardize measurements for scientific and commercial purposes. France played a significant role in promoting and spreading the use of the metric system worldwide. Germany (A), Italy (C), and Spain (D) did not have a direct role in the development of the metric system.
Question 4 of 5
Convert 250 milliliters to liters.
Correct Answer: B
Rationale: To convert milliliters to liters, we must divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 250 milliliters divided by 1000 equals 0.25 liters (choice B). Choice A is incorrect as it is 10 times the correct answer. Choice C is incorrect as it is 5 times the correct answer. Choice D is incorrect as it is 1/10th of the correct answer. Thus, the correct conversion is 0.25 liters.
Question 5 of 5
What is 0.1 liter converted to milliliters?
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.
