1. What is 0.004 as a simplified ratio?

• A. 1:250
• B. 4:35
• C. 7:28
• D. 4:00

Correct answer: A

Rationale: To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250. Choice B, 4:35, is incorrect as it does not reflect the correct conversion. Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004. Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.

2. Convert 0.29 pounds to ounces.

• A. 2.9 ounces
• B. 4.64 ounces
• C. 29 ounces
• D. 46.4 ounces

Correct answer: B

Rationale: To convert pounds to ounces, you need to know that there are 16 ounces in a pound. Multiplying 0.29 pounds by 16 gives you 4.64 ounces. Therefore, the correct answer is B. Choice A (2.9 ounces) is incorrect as it doesn't consider the conversion factor of 16 ounces per pound. Choice C (29 ounces) and Choice D (46.4 ounces) are incorrect because they incorrectly interpret the conversion from pounds to ounces.

3. How many ounces is equal to 1 gram?

• A. 0.015 ounces
• B. 0.035 ounces
• C. 0.045 ounces
• D. 0.055 ounces

Correct answer: B

Rationale: To convert grams to ounces, you need to multiply the weight in grams by 0.035 to get the equivalent weight in ounces. Therefore, 1 gram is equal to 0.035 ounces. Choices A, C, and D are incorrect conversions and do not accurately represent the conversion factor from grams to ounces.

4. Convert 0.1 liter to milliliters.

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

Correct answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.1 liter converts to 100 ml. Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter. Choice C (1000 ml) is incorrect as it represents 1 liter. Choice D (1 ml) is significantly less than the correct conversion.

5. How many millimeters are in 1 centimeter?

• A. 1 mm
• B. 10 mm
• C. 100 mm
• D. 1,000 mm

Correct answer: B

Rationale: The correct answer is B: '10 mm'. There are 10 millimeters in 1 centimeter. To convert centimeters to millimeters, you multiply by 10 because 1 centimeter is equivalent to 10 millimeters. Choice A '1 mm' is incorrect as it represents the size of 1 millimeter, not the conversion from centimeters to millimeters. Choice C '100 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter. Choice D '1,000 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter.
