1. How many feet are equal to 1 yard?

• A. 4 feet
• B. 3 feet
• C. 2 feet
• D. 5 feet

Correct answer: B

Rationale: The correct answer is B: 3 feet. This is because 1 yard is equivalent to 3 feet. The conversion factor between yards and feet is 1 yard = 3 feet. Choice A (4 feet) is incorrect as it represents the conversion of 1 yard to 4 feet, which is inaccurate. Choice C (2 feet) is incorrect as it underestimates the number of feet in 1 yard. Choice D (5 feet) is incorrect as it overestimates the number of feet in 1 yard.

2. How many ounces are in one gallon?

• A. 64 ounces
• B. 128 ounces
• C. 100 ounces
• D. 150 ounces

Correct answer: B

Rationale: The correct answer is B: 128 ounces. One gallon is equivalent to 128 ounces. This conversion relationship is commonly used in cooking, baking, and various liquid measurements. Choice A (64 ounces) is incorrect as it represents half the amount of a gallon. Choice C (100 ounces) and Choice D (150 ounces) are also incorrect, as they do not accurately reflect the conversion of a gallon to ounces.

3. What does 'km' stand for in the metric system?

• A. kilometer
• B. kilomole
• C. kilobyte
• D. knot

Correct answer: A

Rationale: In the metric system, 'km' stands for kilometer, which is a unit of length equal to 1,000 meters. This choice is correct as 'kilometer' is the standard unit for measuring long distances. Choice B, 'kilomole,' is incorrect as it is a unit in chemistry representing a quantity of substance. Choice C, 'kilobyte,' is incorrect as it is a unit of digital information storage, not a unit of measurement. Choice D, 'knot,' is incorrect as it is a unit of speed used in navigation and aeronautics, not a unit of length in the metric system.

4. How many millimeters are in 0.75 centimeters?

• A. 7.5 mm
• B. 0.75 mm
• C. 75 mm
• D. 75 cm

Correct answer: C

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 0.75 centimeters equals 0.75 x 10 = 7.5 millimeters, not 75 millimeters (Choice C). Choice A (7.5 mm) is the correct conversion, while Choice B (0.75 mm) and Choice D (75 cm) are incorrect conversions.

5. How many kilograms are in 1,500 grams?

• A. 0.15 kg
• B. 1.5 kg
• C. 15 kg
• D. 150 kg

Rationale: To convert grams to kilograms, you divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 1,500 grams divided by 1,000 equals 1.5 kilograms, making choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert grams to kilograms.
