1. Convert 5,000 milligrams to grams.

• A. 50 grams
• B. 5 grams
• C. 500 grams
• D. 0.05 grams

Correct answer: B

Rationale: To convert milligrams to grams, you need to divide by 1,000 since there are 1,000 milligrams in 1 gram. Therefore, 5,000 milligrams is equal to 5 grams (5,000 ÷ 1,000 = 5). Choice A, '50 grams,' is incorrect as it results from multiplying instead of dividing. Choice C, '500 grams,' is incorrect as it incorrectly multiplies the value. Choice D, '0.05 grams,' is incorrect as it is the result of dividing by 10 instead of 1,000.

2. What is the result of multiplying 0.15 by 60?

• A. 9
• B. 15
• C. 45
• D. 60

Correct answer: A

Rationale: The correct answer is A: 9. To find the result of multiplying 0.15 by 60, you simply multiply the two numbers together. 0.15 * 60 = 9. This calculation involves basic multiplication. Choices B, C, and D are incorrect as they do not reflect the correct product of 0.15 and 60. Understanding how to multiply decimals and whole numbers is essential in various real-life scenarios such as calculating percentages or adjusting measurements.

3. The metric prefix of Tera is abbreviated as T- and has a value of 10^12. What does Tera mean numerically?

• A. 10^6
• B. 10^9
• C. 10^12
• D. 10^3

Correct answer: C

Rationale: The correct answer is C: 10^12. Tera represents a numerical value of 10^12, which is equivalent to one trillion. It is commonly used in computing and other fields to denote large-scale measurements. Choice A, 10^6, is incorrect as it corresponds to the metric prefix 'Mega.' Choice B, 10^9, is incorrect and corresponds to the metric prefix 'Giga.' Choice D, 10^3, is incorrect and corresponds to the metric prefix 'Kilo.' Therefore, the correct interpretation of the metric prefix Tera is 10^12.

4. 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.

5. What is 0.5 liters in milliliters?

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

Correct answer: A

Rationale: 0.5 liters is equivalent to 500 milliliters. The conversion from liters to milliliters involves multiplying by 1000 since there are 1000 milliliters in a liter. Therefore, the correct answer is 500 ml. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. 50 ml is the conversion for 0.05 liters, 5 ml for 0.005 liters, and 0.5 ml for 0.0005 liters.
