1. How many liters are in 750 milliliters?

• A. 7.5 liters
• B. 0.75 liters
• C. 0.0075 liters
• D. 0.075 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.

2. 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.

3. What does 'mg' stand for in the metric system?

• A. microgram
• B. milligram
• C. gigabyte
• D. megagram

Correct answer: B

Rationale: 'mg' stands for milligram, which is equal to 1/1,000th of a gram. In the metric system, 'microgram' (choice A) is represented by 'mcg', 'gigabyte' (choice C) is a unit of digital information storage, and 'megagram' (choice D) is equivalent to a metric ton.

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. Convert 345,000 millimeters to centimeters (cm).

• A. 34,500 cm
• B. 3,450 cm
• C. 345,000 cm
• D. 345,000,000 cm

Correct answer: B

Rationale: To convert millimeters to centimeters, you need to divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 345,000 mm ÷ 10 = 34,500 cm. Choice A is incorrect because it is a factor of 10 higher than the correct answer. Choice C is incorrect because it represents the original quantity in centimeters, not the converted value. Choice D is incorrect as it erroneously multiplies the millimeters by 1,000 instead of dividing by 10 to convert to centimeters.
