1. 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.

2. 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.

3. Convert 0.004 to a ratio.

• A. 1:250
• B. 4:200
• C. 2:400
• D. 9:200

Correct answer: A

Rationale: To convert 0.004 to a ratio, we can express it as 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice B (4:200) is incorrect as it simplifies to 1:50, not 1:250. Choice C (2:400) simplifies to 1:200, which is also incorrect. Choice D (9:200) simplifies to a ratio greater than 1:1, which is not equivalent to 1:250.

4. How many liters are in 3,000 milliliters?

• A. 0.3 liters
• B. 30 liters
• C. 3 liters
• D. 0.03 liters

Correct answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,000 milliliters / 1,000 = 3 liters. Choice A '0.3 liters' is incorrect as it represents 300 milliliters, not 3,000. Choice B '30 liters' is incorrect as it is the result of multiplying by 10 instead of dividing by 1,000. Choice D '0.03 liters' is incorrect as it represents 30 milliliters, not 3,000.

5. What is 0.07 expressed as a fraction?

• A. 7/100
• B. 1/10
• C. 1/20
• D. 1/50

Correct answer: A

Rationale: To convert a decimal to a fraction, we read the decimal as '7 hundredths,' which is written as 7/100. This fraction is already in its simplest form. Choice B, 1/10, is incorrect as it represents 0.1, not 0.07. Choices C and D, 1/20 and 1/50 respectively, do not match the decimal 0.07.
