1. What is the equivalent of 35.4 centimeters in kilometers (km)?

• A. 0.00354 km
• B. 0.000354 km
• C. 0.00345 km
• D. 0.0345 km

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 35.4 cm ÷ 100,000 = 0.000354 km. Choice A (0.00354 km) is incorrect as it represents dividing by 10,000, not 100,000. Choice C (0.00345 km) is incorrect as the last digit is different from the correct answer. Choice D (0.0345 km) is incorrect as it represents dividing by 1,000, not by 100,000.

2. Which of the following is equal to 0.16 inches?

• A. 0.016 inches
• B. 0.16 inches
• C. 1.6 inches
• D. 16 inches

Correct answer: B

Rationale: The correct answer is B: 0.16 inches. This value is already in its simplest form and represents sixteen one-hundredths of an inch. Choice A, 0.016 inches, is incorrect as it represents sixteen thousandths of an inch, not the given value. Choice C, 1.6 inches, is incorrect as it represents one and six-tenths inches, which is larger than the given value. Choice D, 16 inches, is incorrect as it represents sixteen inches, which is significantly larger than the given value of 0.16 inches.

3. The prefix giga is represented by the following notation ________.

• A. G
• B. m
• C. Gg
• D. g

Correct answer: A

Rationale: The correct answer is A: 'G'. The prefix 'giga' is commonly represented by the letter 'G' and corresponds to a factor of 10^9, which is equivalent to one billion. Choice B, 'm', represents the prefix 'milli', which corresponds to a factor of 10^-3, not 'giga'. Choice C, 'Gg', is incorrect as the prefix 'giga' is represented by a single letter 'G', not 'Gg'. Choice D, 'g', is incorrect as it represents the prefix 'gram' in the International System of Units (SI) and not the prefix 'giga'.

4. What mnemonic helps in recalling metric conversions?

• A. King Hector Died By Drinking Chocolate Milk
• B. Kittens Have Delighted By Dancing Cool Moves
• C. Memorize Your Units Well
• D. Convert These Every Time

Correct answer: A

Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-. Choice B does not provide a relevant mnemonic for metric conversions. Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.

5. How many grams are in one kilogram?

• A. 100 grams
• B. 1000 grams
• C. 500 grams
• D. 2000 grams

Correct answer: B

Rationale: The correct answer is B: 1000 grams. This is because by definition, 1 kilogram is equal to 1000 grams. Choice A, 100 grams, is incorrect as it underestimates the actual conversion. Choice C, 500 grams, and Choice D, 2000 grams, are also incorrect as they do not align with the correct conversion factor of 1 kilogram to 1000 grams.
