Metric Conversions for TEAS 7 Questions
Question 1 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 2 of 5
What is 0.75 as a fraction?
Correct Answer: A
Rationale: To convert 0.75 to a fraction, we write it as 75/100 and simplify to 3/4 by dividing both numerator and denominator by the greatest common divisor, which is 25. Choice A (3/4) is correct as it represents 0.75 in simplest form. Choices B, C, and D are incorrect because they do not equal 0.75 when converted to a fraction. Choice B (7/10) simplifies to 0.7, choice C (15/20) simplifies to 0.75 but is not in simplest form, and choice D (1/2) simplifies to 0.5.
Question 3 of 5
What is 0.4 grams in milligrams?
Correct Answer: A
Rationale: To convert grams to milligrams, you multiply by 1000 since 1 gram = 1000 milligrams. Therefore, 0.4 grams x 1000 = 400 mg. Choice A (400 mg) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 gram = 1000 milligrams.
Question 4 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 5 of 5
What is 0.5 liters in ml?
Correct Answer: A
Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter = 1000 ml. Therefore, 0.5 liters x 1000 = 500 ml. Thus, the correct answer is A (500 ml). Choice B (50 ml) is incorrect as it is 10 times smaller than the correct answer. Choice C (5 ml) is incorrect as it is 100 times smaller than the correct answer. Choice D (0.5 ml) is incorrect as it is the same value in milliliters, not the conversion of liters to milliliters.
