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. What does the prefix 'Tera' refer to?

• A. 10^12
• B. 10^9
• C. 10^15
• D. 10^6

Correct answer: A

Rationale: The prefix 'Tera' corresponds to a factor of 10^12, which is equivalent to one trillion. It is commonly used in various fields like data storage to denote large quantities. Choice B, '10^9,' is incorrect as it corresponds to the prefix 'Giga.' Choice C, '10^15,' is incorrect as it corresponds to the prefix 'Peta.' Choice D, '10^6,' is incorrect as it corresponds to the prefix 'Mega.' Therefore, the correct answer is A.

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

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

Correct answer: B

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.

4. What is 0.03 as a fraction?

• A. 3/100
• B. 1/30
• C. 1/3
• D. 1/10

Correct answer: A

Rationale: To convert a decimal to a fraction, you place the decimal value over a power of 10, where the number of zeros in the denominator is equal to the number of decimal places in the decimal. In this case, 0.03 can be written as 3/100 because there are two decimal places (hundredths). This fraction is already in simplest form. Choice B, 1/30, is incorrect as it represents 0.033 as a fraction. Choice C, 1/3, is incorrect as it represents 0.3 as a fraction. Choice D, 1/10, is incorrect as it represents 0.1 as a fraction.

5. Convert 0.075 mg to micrograms.

• A. 75 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000, not 10000. Therefore, to convert 0.075 mg to mcg, you multiply 0.075 by 1000, giving you 75 mcg. The correct answer is not provided in the choices, and the correct conversion is 75 mcg, which is not listed as an option. Choices A, B, and C are incorrect because they do not reflect the correct conversion factor. Choice D, 750 mcg, is a common mistake made by incorrectly adding a zero. It is important to remember that the conversion from milligrams to micrograms involves multiplying by 1000, not adding extra zeros.
