1. 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.

2. What is the base unit for mass in the metric system?

• A. milligrams
• B. grams
• C. kilograms
• D. tons

Correct answer: B

Rationale: The base unit for mass in the metric system is grams. Grams are the fundamental unit of mass in the metric system, representing smaller quantities than kilograms and tons. Milligrams are a smaller unit of mass, kilograms are a larger unit, and tons are even larger units. Therefore, the correct choice is grams.

3. What is 0.5 liter in ounces?

• A. 16.91 oz
• B. 15.91 oz
• C. 17.91 oz
• D. 18.91 oz

Correct answer: A

Rationale: To convert liters to ounces, you need to multiply the liter value by 33.814. Therefore, to convert 0.5 liters to ounces, you would calculate 0.5 x 33.814 = 16.91 ounces. This conversion factor is commonly used in cooking and liquid measurements. Choice B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.

4. How many milligrams are in 1 gram?

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

Correct answer: D

Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.

5. What is 0.02 as a ratio?

• A. 1:50
• B. 1:20
• C. 2:100
• D. 4:20

Correct answer: C

Rationale: To convert 0.02 to a ratio, you need to express it as a fraction. 0.02 is equivalent to 2/100. Simplifying this fraction gives you 1/50. So, the correct ratio for 0.02 is 1:50. Choice A is correct because it accurately represents the ratio of 0.02. Choices B, C, and D are incorrect: B is not the simplified form of 0.02, C simplifies to 1:50, not 2:40, and D is not the correct simplified ratio for 0.02.
