1. What is 0.02 as a ratio?

• A. 1:50
• B. 1:20
• C. 2:100
• D. 4:20

Correct answer: C

Rationale: To convert 0.02 to a ratio, you need to express it as a fraction. 0.02 is equivalent to 2/100. Simplifying this fraction gives you 1/50. So, the correct ratio for 0.02 is 1:50. Choice A is correct because it accurately represents the ratio of 0.02. Choices B, C, and D are incorrect: B is not the simplified form of 0.02, C simplifies to 1:50, not 2:40, and D is not the correct simplified ratio for 0.02.

2. What is 0.2 rounded to the nearest tenth?

• A. 0.1
• B. 0.2
• C. 0.3
• D. 0.25

Correct answer: B

Rationale: The decimal 0.2 is already at the nearest tenth, so it does not need to be rounded. Rounding to the nearest tenth means keeping one decimal place, which is already the case with 0.2. Therefore, the correct answer is 0.2, as it is already at the specified rounding point. Choices A, C, and D are incorrect because they represent values that are not the result of rounding 0.2 to the nearest tenth. 0.1 is rounding down, 0.3 is rounding up, and 0.25 is not the nearest tenth of 0.2.

3. What is the equivalent of 0.3 mg in mcg?

• A. 300 mcg
• B. 30 mcg
• C. 3000 mcg
• D. 3 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages. Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg. Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000. Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.

4. Convert 1.25 kilograms to grams.

• A. 12.5 grams
• B. 125 grams
• C. 1,250 grams
• D. 1250 mg

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 1.25 kilograms is equal to 1.25 x 1000 = 1,250 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.

5. How many yards are in one mile?

• A. 1760 yards
• B. 1500 yards
• C. 2000 yards
• D. 1800 yards

Correct answer: A

Rationale: The correct answer is A: 1760 yards. There are 1760 yards in one mile. This conversion is a standard unit of measurement in the imperial system. Choice B, 1500 yards, is incorrect as it is not the correct conversion from miles to yards. Choice C, 2000 yards, is also incorrect as it does not represent the accurate conversion. Choice D, 1800 yards, is incorrect as it does not reflect the correct number of yards in a mile according to the established conversion rate.
