1. What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?

• A. 115.7 kg
• B. 126.0 kg
• C. 115.8 kg
• D. 115.6 kg

Correct answer: D

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.

2. How many milliliters are there in 0.5 liters?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters is equal to 500 milliliters. Choices B, C, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.

3. How many milliliters are in 1 ounce?

• A. 20 ml
• B. 30 ml
• C. 40 ml
• D. 50 ml

Correct answer: B

Rationale: The correct answer is B: 30 ml. 1 ounce is equivalent to 30 milliliters. This conversion is a common one in many contexts involving liquid measurements. Choice A (20 ml), Choice C (40 ml), and Choice D (50 ml) are incorrect conversions and do not represent the accurate conversion between ounces and milliliters.

4. What is 0.004 as a ratio?

• A. 5:10
• B. 1:250
• C. 7:28
• D. 4:00

Correct answer: B

Rationale: To convert 0.004 to a ratio, first express it as a fraction by writing it as 4/1000. Simplifying this fraction gives 1/250. Therefore, 0.004 as a ratio is 1:250. Choice A (5:10) simplifies to 1:2, not equivalent to 0.004. Choice C (7:28) does not simplify to a value close to 0.004. Choice D (4:00) is not a valid ratio representation of 0.004.

5. What is 0.875 as a simplified fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.
