1. 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.

2. Convert 0.04 grams to milligrams.

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

Correct answer: A

Rationale: To convert 0.04 grams to milligrams, you need to multiply by 1000, not 10000. Therefore, 0.04 grams equals 40 milligrams (0.04g * 1000 = 40mg). Choice B, '4 mg,' is incorrect as it reflects the value as if it was in grams. Choice C, '400 mg,' is incorrect as it incorrectly multiplies by 100 instead of 1000. Choice D, '0.4 mg,' is incorrect as it incorrectly moves the decimal point to the right instead of multiplying by 1000.

3. Convert 5,000 milligrams to grams.

• A. 50 grams
• B. 5 grams
• C. 500 grams
• D. 0.05 grams

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 since there are 1,000 milligrams in 1 gram. Therefore, 5,000 milligrams is equal to 5 grams (5,000 ÷ 1,000 = 5). Choice A, '50 grams,' is incorrect as it results from multiplying instead of dividing. Choice C, '500 grams,' is incorrect as it incorrectly multiplies the value. Choice D, '0.05 grams,' is incorrect as it is the result of dividing by 10 instead of 1,000.

4. What is 0.5 liters in ml?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters equals 500 milliliters. This conversion is commonly used in various fields such as cooking, medicine, and science. Choice B, 50 ml, is incorrect as it represents 0.05 liters, not 0.5 liters. Choice C, 5 ml, is even smaller and represents 0.005 liters. Choice D, 0.5 ml, is incorrect as it is a tenth of the correct conversion.

5. How many pints are in one quart?

• A. 1 pint
• B. 2 pints
• C. 3 pints
• D. 4 pints

Correct answer: B

Rationale: The correct answer is B: 2 pints. There are 2 pints in one quart. A quart is equivalent to 2 pints, so each quart contains 2 pints. Choice A, 1 pint, is incorrect because a quart consists of more than 1 pint. Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.
