1. 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.

2. What is 0.03 as a fraction?

• A. 3/100
• B. 1/30
• C. 1/3
• D. 1/10

Correct answer: A

Rationale: To convert a decimal to a fraction, you place the decimal value over a power of 10, where the number of zeros in the denominator is equal to the number of decimal places in the decimal. In this case, 0.03 can be written as 3/100 because there are two decimal places (hundredths). This fraction is already in simplest form. Choice B, 1/30, is incorrect as it represents 0.033 as a fraction. Choice C, 1/3, is incorrect as it represents 0.3 as a fraction. Choice D, 1/10, is incorrect as it represents 0.1 as a fraction.

3. Convert 0.5 liters to milliliters.

• A. 50 ml
• B. 500 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 as there are 1000 milliliters in 1 liter. Therefore, when converting 0.5 liters to milliliters, the correct answer is 0.5 x 1000 = 500 ml. Choice A (50 ml) is incorrect because it represents the conversion of 0.05 liters, not 0.5 liters. Choice C (5 ml) is incorrect as it represents the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it does not reflect the correct conversion from liters to milliliters.

4. What is the formula for calculating the volume of a solid object?

• A. V = W/L
• B. V = L x W x H
• C. V = W/H
• D. V = L/W

Correct answer: B

Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H, where L represents the length, W represents the width, and H represents the height. Choice A (V = W/L) is incorrect as it represents a division operation, not multiplication. Choice C (V = W/H) is incorrect as it does not account for the width and height. Choice D (V = L/W) is incorrect as it represents the inverse operation of what is needed to calculate volume.

5. 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.
