1. What is 0.5 x 200?

• A. 100
• B. 50
• C. 150
• D. 200

Correct answer: A

Rationale: To find the product of 0.5 and 200, you multiply the two numbers, which equals 100. The correct answer is A. Choice B, 50, is the result of multiplying 0.5 by 100 instead of 200. Choice C, 150, is the result of adding 0.5 and 200 instead of multiplying them. Choice D, 200, is the second number in the multiplication operation and not the correct product.

2. What is 0.75 as a fraction?

• A. 3/4
• B. 7/10
• C. 15/20
• D. 1/2

Correct answer: A

Rationale: To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal part as the numerator and a power of 10 as the denominator. In this case, 0.75 can be written as 75/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives you 3/4. Therefore, the correct answer is A. Choice B (7/10), Choice C (15/20), and Choice D (1/2) are incorrect because they do not represent the correct conversion of 0.75 into a fraction.

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. How many milligrams are in 2 grams?

• A. 200 mg
• B. 2,000 mg
• C. 20 mg
• D. 20,000 mg

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 2 grams is equal to 2,000 milligrams. Choice A (200 mg) is incorrect as it represents 0.2 grams. Choice C (20 mg) is incorrect as it represents 0.02 grams. Choice D (20,000 mg) is incorrect as it represents 20 grams.

5. Convert 5 kilometers to meters.

• A. 50 meters
• B. 500 meters
• C. 5000 meters
• D. 0.5 meters

Correct answer: C

Rationale: To convert kilometers to meters, you need to multiply by 1000 because there are 1000 meters in 1 kilometer. Therefore, 5 kilometers x 1000 = 5000 meters. Choice A (50 meters) is incorrect because it underestimates the conversion. Choice B (500 meters) is incorrect as it also underestimates the conversion. Choice D (0.5 meters) is incorrect as it incorrectly represents the conversion as less than a kilometer.
