1. What is 0.875 as a fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, you can write it as 875/1000. Simplifying this fraction by dividing the numerator and denominator by their greatest common divisor, which is 125, gives you 7/8. Therefore, the correct answer is 7/8. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are incorrect as they do not represent the fraction equivalent of 0.875.

2. How many milliliters are in 2 liters?

• A. 2000 mL
• B. 20,000 mL
• C. 200 mL
• D. 2 mL

Correct answer: A

Rationale: There are 1000 milliliters in 1 liter, so 2 liters equal 2000 milliliters. The conversion is based on the fact that the prefix 'milli-' means one-thousandth. Therefore, the correct answer is 2000 mL. Choice B, 20,000 mL, is incorrect as it multiplies 2 liters by 10. Choice C, 200 mL, is incorrect as it divides 2 liters by 10. Choice D, 2 mL, is incorrect as it incorrectly assumes that 2 liters is equal to 2 milliliters.

3. How many millimeters are in 1 centimeter?

• A. 1 mm
• B. 10 mm
• C. 100 mm
• D. 1,000 mm

Correct answer: B

Rationale: The correct answer is B: '10 mm'. There are 10 millimeters in 1 centimeter. To convert centimeters to millimeters, you multiply by 10 because 1 centimeter is equivalent to 10 millimeters. Choice A '1 mm' is incorrect as it represents the size of 1 millimeter, not the conversion from centimeters to millimeters. Choice C '100 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter. Choice D '1,000 mm' is incorrect as it is the equivalent of 1 meter, not 1 centimeter.

4. 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.

5. Convert 0.5 liters to milliliters.

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

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 as there are 1000 milliliters in 1 liter. Therefore, when converting 0.5 liters to milliliters, the correct answer is 0.5 x 1000 = 500 ml. Choice A (50 ml) is incorrect because it represents the conversion of 0.05 liters, not 0.5 liters. Choice C (5 ml) is incorrect as it represents the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it does not reflect the correct conversion from liters to milliliters.
