1. What is 0.26 as a fraction in simplest form?

• A. 13/50
• B. 26/100
• C. 26/1000
• D. 1/4

Correct answer: A

Rationale: To convert 0.26 to a fraction, we write it as 26/100. To simplify this fraction, we divide both the numerator and the denominator by their greatest common divisor, which is 2 in this case. Dividing 26 and 100 by 2 results in 13/50. Therefore, 0.26 as a fraction in simplest form is 13/50. Choice B (26/100) is the original form of the decimal, not simplified. Choice C (26/1000) is incorrect as it doesn't match the decimal representation. Choice D (1/4) is not the equivalent fraction for 0.26.

2. Where was the metric system developed?

• A. Germany
• B. France
• C. Italy
• D. Spain

Correct answer: B

Rationale: The metric system was developed in France during the 1790s as a standardized system of measurement. This choice is correct because the metric system originated in France. Germany, Italy, and Spain did not play a role in the development of the metric system, making choices A, C, and D incorrect.

3. How many milliliters are in 0.5 liters?

• A. 50 mL
• B. 500 mL
• C. 5,000 mL
• D. 5 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 0.5 liters x 1000 = 500 milliliters, making choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters.

4. What is the metric prefix for 10^-12 and how does it relate to meters?

• A. pico- (p) = 10^-12 meters
• B. nano- (n) = 10^-12 meters
• C. femto- (f) = 10^-12 meters
• D. pico- (p) = 10^-15 meters

Correct answer: C

Rationale: The prefix 'femto-' stands for 10^-15, making femtometer equal to 10^-15 meters. The incorrect choices are A and B because 'pico-' represents 10^-12 (picometer) and 'nano-' represents 10^-9 (nanometer), respectively. Choice D is also incorrect as 'pico-' is associated with 10^-12, not 10^-15.

5. 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.
