1. Convert 0.75 kilograms to grams.

• A. 75 grams
• B. 750 grams
• C. 7,500 grams
• D. 75,000 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.75 kilograms is equal to 0.75 x 1000 = 750 grams. Choices A, C, and D are incorrect as they incorrectly place the decimal point and do not reflect the correct conversion from kilograms to grams.

2. Convert 345 kilometers to meters (m).

• A. 345,000 m
• B. 34,500 m
• C. 34,500,000 m
• D. 345,000,000 m

Correct answer: B

Rationale: To convert kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in a kilometer. Therefore, 345 km multiplied by 1,000 equals 345,000 meters. Choice A is incorrect as it incorrectly places the comma. Choice C is incorrect as it adds an extra zero at the end. Choice D is incorrect as it adds an extra zero at the beginning, resulting in an incorrect conversion.

3. What is 0.4 divided by 40?

• A. 1/100
• B. 1/1000
• C. 1/400
• D. 1/40000

Correct answer: B

Rationale: The calculation of 0.4 divided by 40 results in 0.01, which can be expressed as 1/100. This fraction is the correct representation of the division of 0.4 by 40. Choice A, 1/100, is the correct answer as it accurately reflects the division. Choices C and D, 1/400 and 1/40000 respectively, do not correctly represent the division operation performed on 0.4 and 40, leading to incorrect results and are therefore not the correct answers.

4. Convert 0.1 liter to milliliters.

• A. 10 ml
• B. 100 ml
• C. 1000 ml
• D. 1 ml

Correct answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.1 liter converts to 100 ml. Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter. Choice C (1000 ml) is incorrect as it represents 1 liter. Choice D (1 ml) is significantly less than the correct conversion.

5. How many grams are in 5 kilograms?

• A. 50 grams
• B. 500 grams
• C. 5000 grams
• D. 5 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 because there are 1000 grams in a kilogram. Therefore, 5 kilograms x 1000 grams/kilogram = 5000 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.
