1. Convert 1.5 kilometers to meters.

• A. 1,500 meters
• B. 150 meters
• C. 15,000 meters
• D. 1.5 meters

Correct answer: A

Rationale: To convert kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in a kilometer. Therefore, 1.5 kilometers is equal to 1,500 meters (1.5 x 1,000 = 1,500). Choice A, '1,500 meters,' is the correct answer. Choice B, '150 meters,' is incorrect as it represents converting 0.15 kilometers to meters. Choice C, '15,000 meters,' is incorrect as it represents multiplying by 10,000 instead of 1,000. Choice D, '1.5 meters,' is incorrect as it doesn't convert the kilometers to meters accurately.

2. Which basic SI conversion is incorrect?

• A. 1 cm = 10 mm
• B. 1 m = 100 cm
• C. 1 km = 1000 m
• D. 1 g = 100 mg

Correct answer: D

Rationale: The correct SI conversion for grams (g) to milligrams (mg) is 1 g = 1000 mg, not 100 mg. Therefore, option D is incorrect. Option A is correct as 1 cm is equal to 10 mm, option B is correct as 1 m equals 100 cm, and option C is correct as 1 km is equivalent to 1000 m. Understanding these basic SI conversions is essential for accurate measurements and calculations in various scientific fields.

3. 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.

4. How many kilograms are in 1,500 grams?

• A. 0.15 kg
• B. 1.5 kg
• C. 15 kg
• D. 150 kg

Correct answer: B

Rationale: To convert grams to kilograms, you divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 1,500 grams divided by 1,000 equals 1.5 kilograms, making choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert grams to kilograms.

5. Convert 0.875 to a fraction,

• A. 7\8
• B. 8\7
• C. 3\4
• D. 9\10

Correct answer: A

Rationale: To convert 0.875 to a fraction, express it as 875\10000. Simplifying this fraction by dividing both the numerator and denominator by 125 results in 7\80.
