1. Convert 0.0345 kilograms to grams (g).

• A. 3.45 grams
• B. 34.5 grams
• C. 345 grams
• D. 3450 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since 1 kilogram is equal to 1,000 grams. Therefore, 0.0345 kg multiplied by 1,000 equals 34.5 grams. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. A states 3.45 grams, which is off by a factor of 10. C and D overestimate the conversion by considering the decimal point in the original value as a whole number. Hence, the correct answer is B, 34.5 grams.

2. Convert 100 grams to kilograms.

• A. 0.1 kg
• B. 1 kg
• C. 10 kg
• D. 0.01 kg

Correct answer: A

Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in a kilogram. So, 100 grams divided by 1000 equals 0.1 kilograms, making choice A the correct answer. Choices B, C, and D are incorrect because they do not involve the correct conversion factor or calculation. Choice B of 1 kg is the equivalent of 1000 grams, which is 10 times the given value of 100 grams, making it too large. Choice C of 10 kg is 100 times the given value, and choice D of 0.01 kg is 10 times smaller than the correct conversion.

3. What is 0.875 as a simplified fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.

4. 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.

5. What is 0.025 mg converted to micrograms?

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000, not 10000. Therefore, 0.025 mg is equal to 25 mcg. The correct conversion is obtained by recognizing that 1 milligram (mg) is equal to 1000 micrograms (mcg). Choices B, C, and D are incorrect because they do not correctly convert milligrams to micrograms. Choice B is 10 times the correct answer, choice C is 100 times less, and choice D is 100 times less than the correct conversion.
