1. What is the equivalent of 3,450 milliliters in liters (L)?

• A. 0.345 liters
• B. 3.45 liters
• C. 34.5 liters
• D. 345 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,450 mL ÷ 1,000 = 3.45 liters. Choice A (0.345 liters) is incorrect as it incorrectly moves the decimal point. Choice C (34.5 liters) is incorrect as it overestimates the conversion. Choice D (345 liters) is incorrect as it overestimates by an order of magnitude.

2. 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.

3. What is 0.025 mg in mcg?

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in a milligram. Therefore, 0.025 mg x 1000 = 25 mcg. This means that the correct answer is A, 25 mcg. Choice B, 250 mcg, is incorrect because it incorrectly multiplies by 10 instead of 1000. Choice C, 2.5 mcg, is incorrect as it inaccurately divides the value by 10. Choice D, 0.25 mcg, is also incorrect as it divides the value by 100 instead of multiplying by 1000.

4. How many liters are in 750 milliliters?

• A. 7.5 liters
• B. 0.75 liters
• C. 0.0075 liters
• D. 0.075 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, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.

5. What is 0.05 mg in mcg?

• A. 50 mcg
• B. 500 mcg
• C. 5 mcg
• D. 0.5 mcg

Correct answer: A

Rationale: 0.05 mg is equivalent to 50 mcg because 1 mg is equal to 1000 mcg. To convert milligrams to micrograms, you need to multiply by 1000. Therefore, 0.05 mg x 1000 = 50 mcg. Choices B, C, and D are incorrect because they do not correctly convert milligrams to micrograms. Option B (500 mcg) would be the result if the conversion was done incorrectly by adding an extra zero, while options C (5 mcg) and D (0.5 mcg) are incorrect due to miscalculating the conversion factor.
