1. What is 0.07 as a simplified fraction?

• A. 7/100
• B. 7/50
• C. 7/25
• D. 7/10

Correct answer: A

Rationale: The decimal 0.07 can be expressed as the fraction 7/100, where 7 is the numerator and 100 is the denominator. To simplify the fraction, you divide both the numerator and denominator by their greatest common divisor, which in this case is 1. Therefore, 7/100 is already in its simplest form and cannot be further simplified. Choices B, C, and D are incorrect fractions as they do not represent the decimal 0.07.

2. What is 0.5 liters converted to milliliters?

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

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.5 liters converts to 500 milliliters. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.

3. What is 0.075 mg in mcg?

• A. 0.075 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.075 mg equals 75 * 1000 = 750 mcg. The correct answer is 750 mcg. Choices A, B, and C are incorrect because they do not apply the correct conversion factor of 1000. It is essential to understand these conversions, especially in medical settings where accurate dosing is crucial to avoid errors and ensure patient safety.

4. How many ounces are in 2 quarts?

• A. 8 ounces
• B. 32 ounces
• C. 16 ounces
• D. 64 ounces

Correct answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.

5. 10^6 m can be expressed as ____.

• A. 1 kilometer
• B. 1 megameter
• C. 1 gigameter
• D. 1 terameter

Correct answer: A

Rationale: The correct answer is A: 1 kilometer. 10^6 meters is equivalent to 1 kilometer, not 1 megameter. The prefix 'kilo-' represents a factor of 10^3 or one thousand, which is the appropriate conversion in this case. Choice B, 1 megameter, would be 10^6 meters squared. Choices C and D, 1 gigameter and 1 terameter, would represent even larger distances, as 'giga-' represents 10^9 and 'tera-' represents 10^12.
