1. Convert 25 millimeters to centimeters.

• A. 250 cm
• B. 25 cm
• C. 2.5 mm
• D. 25 mm

Correct answer: D

Rationale: To convert millimeters to centimeters, you need to divide by 10 because there are 10 millimeters in one centimeter. Therefore, 25 millimeters is equal to 25/10 = 2.5 centimeters, making choice D the correct answer. Choice A (250 cm) is incorrect as it incorrectly multiplies instead of dividing by 10. Choice B (25 cm) is also incorrect as it doesn't convert millimeters to centimeters. Choice C (2.5 mm) is incorrect as it provides the measurement in millimeters rather than centimeters.

2. 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.

3. How many feet are equal to 1 yard?

• A. 4 feet
• B. 3 feet
• C. 2 feet
• D. 5 feet

Correct answer: B

Rationale: The correct answer is B: 3 feet. This is because 1 yard is equivalent to 3 feet. The conversion factor between yards and feet is 1 yard = 3 feet. Choice A (4 feet) is incorrect as it represents the conversion of 1 yard to 4 feet, which is inaccurate. Choice C (2 feet) is incorrect as it underestimates the number of feet in 1 yard. Choice D (5 feet) is incorrect as it overestimates the number of feet in 1 yard.

4. What is 0.02 as a ratio?

• A. 1:50
• B. 1:20
• C. 2:100
• D. 4:20

Correct answer: C

Rationale: To convert 0.02 to a ratio, you need to express it as a fraction. 0.02 is equivalent to 2/100. Simplifying this fraction gives you 1/50. So, the correct ratio for 0.02 is 1:50. Choice A is correct because it accurately represents the ratio of 0.02. Choices B, C, and D are incorrect: B is not the simplified form of 0.02, C simplifies to 1:50, not 2:40, and D is not the correct simplified ratio for 0.02.

5. What is 0.3 ml in tsp?

• A. 0.06 tsp
• B. 0.1 tsp
• C. 0.2 tsp
• D. 0.3 tsp

Correct answer: A

Rationale: To convert milliliters to teaspoons, you can use the conversion factor that there are approximately 5 milliliters in a teaspoon. When you divide 0.3 ml by 5, you get 0.06 teaspoons, which is equivalent to 0.06 tsp. Therefore, the correct answer is A. Choice B, 0.1 tsp, is incorrect because it does not result from the conversion of 0.3 ml to tsp. Choice C, 0.2 tsp, is also incorrect as it does not accurately represent the conversion. Choice D, 0.3 tsp, is the same value as the original quantity in milliliters, which is not the correct conversion to teaspoons.
