1. What does 'g' stand for in the metric system?

• A. gram
• B. grain
• C. goose
• D. grammage

Correct answer: A

Rationale: In the metric system, 'g' stands for gram, which is the base unit for mass. Choice B, 'grain,' is a measurement unit in the imperial system and not the metric system. Choice C, 'goose,' is unrelated to the metric system. Choice D, 'grammage,' is a term used to describe the weight of paper or fabric, not a unit in the metric system.

2. Convert 250 milliliters to liters.

• A. 25 liters
• B. 0.25 liters
• C. 2.5 liters
• D. 0.025 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 250 milliliters is equal to 250/1000 = 0.25 liters. Choice A, 25 liters, is incorrect as it is a magnitude higher than the correct answer. Choice C, 2.5 liters, is also incorrect as it is 10 times greater than the correct conversion. Choice D, 0.025 liters, is incorrect as it is a magnitude lower than the correct conversion.

3. What is 0.75 as a fraction?

• A. 3/4
• B. 7/10
• C. 15/20
• D. 1/2

Correct answer: A

Rationale: To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal part as the numerator and a power of 10 as the denominator. In this case, 0.75 can be written as 75/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives you 3/4. Therefore, the correct answer is A. Choice B (7/10), Choice C (15/20), and Choice D (1/2) are incorrect because they do not represent the correct conversion of 0.75 into a fraction.

4. What is 0.875 as a simplified fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.

5. How many micrograms are in 1 milligram?

• A. 1 µg
• B. 10 µg
• C. 100 µg
• D. 1,000 µg

Correct answer: D

Rationale: The correct answer is D: 1,000 µg. To convert milligrams to micrograms, you need to multiply by 1,000 because there are 1,000 micrograms in 1 milligram. Choices A, B, and C are incorrect because they do not correctly convert milligrams to micrograms. 1 milligram is equal to 1,000 micrograms, making choice D the right answer.
