1. How many centimeters are in 4 meters?

• A. 40 cm
• B. 400 cm
• C. 4 cm
• D. 0.4 cm

Correct answer: B

Rationale: To convert meters to centimeters, you multiply by 100. In this case, 4 meters x 100 = 400 centimeters. Therefore, the correct answer is 400 cm. Choices A, C, and D are incorrect because they do not correctly convert meters to centimeters.

2. How many feet are in one mile?

• A. 5000 feet
• B. 5280 feet
• C. 5300 feet
• D. 5500 feet

Correct answer: B

Rationale: The correct answer is B: 5280 feet. One mile is equivalent to 5280 feet. This is a standard conversion that is widely known. Choice A (5000 feet) is incorrect as it is not the exact conversion of a mile. Choice C (5300 feet) and choice D (5500 feet) are also incorrect as they do not represent the accurate conversion from miles to feet.

3. What is 0.5 L converted to mL?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters multiplied by 1000 equals 500 milliliters. Choice A, 500 mL, is the correct answer. Choice B, 50 mL, is incorrect as it represents converting 0.05 liters to milliliters. Choice C, 5 mL, is incorrect as it represents converting 0.005 liters to milliliters. Choice D, 0.5 mL, is incorrect as it represents the original amount in milliliters, not the conversion of liters to milliliters.

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. What is the correct formula to convert Fahrenheit to Celsius?

• A. F = (C × 9/5) + 32
• B. C = (F - 32) × 5/9
• C. C = (F - 32) × 9/5
• D. F = (C + 32) × 5/9

Correct answer: B

Rationale: The correct formula to convert Fahrenheit to Celsius is C = (F - 32) × 5/9. This formula is derived from the relationship between the two temperature scales. The incorrect choices can be ruled out as follows: A. F = (C × 9/5) + 32 - This formula is used to convert Celsius to Fahrenheit. C. C = (F - 32) × 9/5 - This formula incorrectly multiplies by 9/5 instead of dividing. D. F = (C + 32) × 5/9 - This formula does not subtract the constant 32 from the Fahrenheit value.
