1. 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.

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. What is 0.07 expressed as a fraction?

• A. 7/100
• B. 1/10
• C. 1/20
• D. 1/50

Correct answer: A

Rationale: To convert a decimal to a fraction, we read the decimal as '7 hundredths,' which is written as 7/100. This fraction is already in its simplest form. Choice B, 1/10, is incorrect as it represents 0.1, not 0.07. Choices C and D, 1/20 and 1/50 respectively, do not match the decimal 0.07.

4. What is the result of multiplying 0.15 by 60?

• A. 9
• B. 15
• C. 45
• D. 60

Correct answer: A

Rationale: The correct answer is A: 9. To find the result of multiplying 0.15 by 60, you simply multiply the two numbers together. 0.15 * 60 = 9. This calculation involves basic multiplication. Choices B, C, and D are incorrect as they do not reflect the correct product of 0.15 and 60. Understanding how to multiply decimals and whole numbers is essential in various real-life scenarios such as calculating percentages or adjusting measurements.

5. What is 0.4 expressed in inches?

• A. 0.04 inches
• B. 4 inches
• C. 0.4 inches
• D. 40 inches

Correct answer: C

Rationale: To express 0.4 in inches, you don't need to convert it further as it is already in inches. Therefore, the correct answer is 0.4 inches. Choice A (0.04 inches) is incorrect as it represents a smaller quantity. Choice B (4 inches) and Choice D (40 inches) are incorrect as they represent larger quantities, which are not equivalent to 0.4 inches.
