1. What does 'mm' stand for in the metric system?

• A. millimeter
• B. megabyte
• C. millipede
• D. metered

Correct answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

2. What is the correct conversion of 35,400 milligrams to grams (g)?

• A. 35.4 g
• B. 35.4 g
• C. 354 g
• D. 354,000 g

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 because there are 1,000 milligrams in a gram. Therefore, 35,400 mg ÷ 1,000 = 35.4 grams. Choice A is incorrect because it does not account for the conversion from milligrams to grams. Choice C is incorrect as it incorrectly drops a zero, leading to an inaccurate conversion. Choice D is incorrect as it incorrectly multiplies instead of dividing, resulting in a significantly larger value than the correct answer.

3. How many centimeters are in one meter?

• A. 1/10 cm
• B. 100 cm
• C. 10 cm
• D. 1000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. One meter is equivalent to 100 centimeters. This conversion is based on the metric system, where the prefix 'centi-' represents one hundredth. Choices A, C, and D are incorrect because they do not accurately reflect the conversion of meters to centimeters. Choice A, '1/10 cm,' is incorrect as it represents a fraction of a centimeter, not the full conversion from meters to centimeters. Choice C, '10 cm,' is incorrect as it represents the conversion from decimeters to centimeters, not meters to centimeters. Choice D, '1000 cm,' is incorrect as it represents the conversion from meters to millimeters, not centimeters.

4. 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.

5. What is 0.75 as a fraction?

• A. 3/4
• B. 7/10
• C. 15/20
• D. 1/2

Correct answer: A

Rationale: To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal part as the numerator and a power of 10 as the denominator. In this case, 0.75 can be written as 75/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives you 3/4. Therefore, the correct answer is A. Choice B (7/10), Choice C (15/20), and Choice D (1/2) are incorrect because they do not represent the correct conversion of 0.75 into a fraction.
