1. Which of the following is equal to 0.13 inches?

• A. 0.013 inches
• B. 1.3 inches
• C. 0.13 inches
• D. 13 inches

Correct answer: C

Rationale: The correct answer is C: 0.13 inches. When converting decimals to inches, the value remains the same. Choice A, 0.013 inches, represents a smaller value than 0.13 inches as it has an extra zero. Choice B, 1.3 inches, is incorrect as it is a larger value than 0.13 inches. Choice D, 13 inches, is significantly larger than 0.13 inches, making it an incorrect conversion.

2. Convert 0.345 kilometers to meters (m).

• A. 3.45 m
• B. 345 m
• C. 345 cm
• D. 345 m

Correct answer: B

Rationale: To convert kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in 1 kilometer. Therefore, 0.345 km × 1,000 = 345 meters. Choice A (3.45 m) is incorrect because it is the result of a mathematical error; the decimal point was misplaced. Choice C (345 cm) is incorrect as it represents centimeters, not meters. Choice D (345 m) is a duplicate of the correct answer B.

3. What is 0.3 ml in tsp?

• A. 0.06 tsp
• B. 0.1 tsp
• C. 0.2 tsp
• D. 0.3 tsp

Correct answer: A

Rationale: To convert milliliters to teaspoons, you can use the conversion factor that there are approximately 5 milliliters in a teaspoon. When you divide 0.3 ml by 5, you get 0.06 teaspoons, which is equivalent to 0.06 tsp. Therefore, the correct answer is A. Choice B, 0.1 tsp, is incorrect because it does not result from the conversion of 0.3 ml to tsp. Choice C, 0.2 tsp, is also incorrect as it does not accurately represent the conversion. Choice D, 0.3 tsp, is the same value as the original quantity in milliliters, which is not the correct conversion to teaspoons.

4. Convert 0.1 liter to milliliters. What is the equivalent volume?

• A. 1 ml
• B. 10 ml
• C. 100 ml
• D. 1000 ml

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 because there are 1,000 milliliters in a liter. Therefore, 0.1 liter is equal to 100 milliliters. Choice A (1 ml) is incorrect because it represents the conversion of 0.01 liters, not 0.1 liters. Choice B (10 ml) is incorrect as it also represents the conversion of 0.01 liters. Choice D (1000 ml) is incorrect as it represents the conversion of 1 liter, not 0.1 liter.

5. Convert 0.025 mg to micrograms.

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

Correct answer: A

Rationale: To convert milligrams to micrograms, you multiply by 1000, not 10000. Therefore, 0.025 mg equals 25 mcg. Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10000. Choice C (2.5 mcg) is incorrect as it incorrectly divides by 10. Choice D (0.25 mcg) is incorrect as it incorrectly multiplies by 10.
