1. Convert 3.75 liters to milliliters.

• A. 3.75 ml
• B. 375 ml
• C. 3750 ml
• D. 37.5 ml

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 3.75 liters x 1000 = 3750 milliliters. This means that option C, 3750 ml, is the correct conversion. Choices A, B, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.

2. What is the metric equivalent of 1 inch?

• A. 1.54 cm
• B. 2.54 cm
• C. 3.54 cm
• D. 4.54 cm

Correct answer: B

Rationale: The correct answer is B: 2.54 cm. One inch is equivalent to 2.54 centimeters in the metric system. This conversion factor is commonly used in converting measurements between the imperial and metric systems. Choice A (1.54 cm), Choice C (3.54 cm), and Choice D (4.54 cm) are incorrect conversions and do not represent the accurate metric equivalent of 1 inch.

3. Which metric prefix represents 10^-2?

• A. centi
• B. milli
• C. nano
• D. deci

Correct answer: A

Rationale: The metric prefix 'centi-' signifies 10^-2, denoting one-hundredth of a unit. For instance, 1 centimeter equals 0.01 of the base unit. Choice B, 'milli,' represents 10^-3, 'nano' in Choice C represents 10^-9, and 'deci' in Choice D stands for 10^-1. Therefore, the correct answer is 'centi.'

4. What is 0.04 g in mg?

• A. 40 mg
• B. 400 mg
• C. 4 mg
• D. 0.4 mg

Correct answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. Therefore, to convert 0.04 grams to milligrams, you would do 0.04 * 1000 = 40 mg. Choice A, '40 mg,' is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert grams to milligrams. Choice B, '400 mg,' is incorrect because it mistakenly multiplies by 10 instead of 1000. Choice C, '4 mg,' is incorrect because it does not account for the correct conversion factor. Choice D, '0.4 mg,' is incorrect because it underestimates the conversion by a factor of 10.

5. 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.
