1. 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.

2. Convert 0.2 liters to milliliters. What is the equivalent volume?

• A. 20 ml
• B. 200 ml
• C. 2 ml
• D. 2000 ml

Correct answer: B

Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in a liter. So, 0.2 * 1,000 = 200 milliliters. Therefore, the correct answer is 200 ml. Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.

3. How many centimeters are in 1 inch?

• A. 2.54 cm
• B. 3 cm
• C. 2 cm
• D. 1 cm

Correct answer: A

Rationale: The correct answer is A: 2.54 cm. One inch is equivalent to 2.54 centimeters. This conversion factor is commonly used when converting measurements between the metric and imperial systems. Choice B (3 cm) is incorrect as it is not the accurate conversion factor for 1 inch. Choice C (2 cm) is also incorrect as it does not reflect the correct conversion. Choice D (1 cm) is incorrect as it inaccurately states the conversion value for 1 inch.

4. What is the equivalent of 500 milliliters in liters?

• A. 0.05 liters
• B. 0.5 liters
• C. 5 liters
• D. 50 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 500 milliliters divided by 1000 equals 0.5 liters. Choice A (0.05 liters) is incorrect because it represents 50 milliliters, not 500 milliliters. Choice C (5 liters) and Choice D (50 liters) are both incorrect as they are higher values and do not accurately represent the conversion of 500 milliliters to liters.

5. How many grams are in 2 kilograms?

• A. 200 grams
• B. 2000 grams
• C. 20 grams
• D. 2 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, 2 kilograms is equal to 2 x 1000 = 2000 grams. Choice A (200 grams) is incorrect as it represents the value of 0.2 kilograms. Choice C (20 grams) is incorrect as it represents the value of 0.02 kilograms. Choice D (2 grams) is incorrect as it represents the value of 0.002 kilograms.
