1. Which of the following is equal to 0.16 inches?

• A. 0.016 inches
• B. 0.16 inches
• C. 1.6 inches
• D. 16 inches

Correct answer: B

Rationale: The correct answer is B: 0.16 inches. This value is already in its simplest form and represents sixteen one-hundredths of an inch. Choice A, 0.016 inches, is incorrect as it represents sixteen thousandths of an inch, not the given value. Choice C, 1.6 inches, is incorrect as it represents one and six-tenths inches, which is larger than the given value. Choice D, 16 inches, is incorrect as it represents sixteen inches, which is significantly larger than the given value of 0.16 inches.

2. 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.

3. What is 0.2 mg converted to mcg?

• A. 200 mcg
• B. 20 mcg
• C. 2000 mcg
• D. 2 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.2 mg * 1000 = 200 mcg. This is the correct conversion. Choice B (20 mcg) is incorrect because it does not account for multiplying by 1000. Choice C (2000 mcg) is incorrect as it mistakenly multiplies by 10 instead of 1000. Choice D (2 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.

4. The prefix 'milli' stands for 0.001 (10^-3). This means, 1 mm is the same as:

• A. 0.01 m
• B. 0.001 m
• C. 0.1 m
• D. 1 m

Correct answer: B

Rationale: The correct answer is B: '0.001 m.' The prefix 'milli' represents a factor of 10^-3, which means one millimeter (mm) is equivalent to 0.001 meters (m). Therefore, 1 mm is equal to 0.001 m. Choice A, '0.01 m,' is incorrect as it represents 0.01 meters, not 0.001 meters. Choice C, '0.1 m,' is incorrect because it stands for 0.1 meters, which is 10 times greater than 1 mm. Choice D, '1 m,' is incorrect as it represents 1 meter, which is 1000 times greater than 1 mm.

5. What is the equivalent of 0.3 mg in ml?

• A. 0.3 ml
• B. 3 ml
• C. 30 ml
• D. 0.03 ml

Correct answer: A

Rationale: The correct answer is A: 0.3 ml. To convert milligrams (mg) to milliliters (ml), you typically need the substance's density. However, in many medical contexts, especially with liquid medications similar in density to water, 0.3 mg is commonly assumed to be equivalent to 0.3 ml. Choice B (3 ml) is incorrect as it is 10 times greater than the correct conversion. Choice C (30 ml) is incorrect as it is 100 times greater than the correct conversion. Choice D (0.03 ml) is incorrect as it is one-tenth of the correct conversion.
