Question 1 of 9

What is 0.16 as a fraction?

Correct Answer: C

Rationale: To convert 0.16 into a fraction, you write it as 16\100, which simplifies to 4\25. This fraction is in its simplest form and accurately represents the original decimal value without further reduction. Choice A (16\1000) is incorrect because the fraction is not simplified, and Choice D (4\50) is incorrect as it simplifies to 2\25, not representing the original decimal value. Therefore, Choice C is the correct answer.

Question 2 of 9

Convert 0.5 centimeters to millimeters.

Correct Answer: A

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since 1 centimeter equals 10 millimeters. Therefore, 0.5 centimeters is equal to 5 millimeters (0.5 * 10 = 5). Choice A, '5 mm,' is the correct answer. Choice B, '0.5 mm,' is incorrect as it would be equivalent to half a millimeter. Choice C, '50 mm,' is incorrect as it represents 50 millimeters, which would be the equivalent of 5 centimeters. Choice D, '0.05 mm,' is incorrect as it represents 0.05 millimeters, which is a fraction of 1 millimeter.

Question 3 of 9

What is 0.5 liters equivalent to?

Correct Answer: A

Rationale: 0.5 liters is equivalent to 500 milliliters. This conversion is straightforward because 1 liter equals 1000 milliliters. Choice A is correct because it accurately converts 0.5 liters into milliliters. Choices B, C, and D are incorrect as they do not correctly convert the given volume into milliliters.

Question 4 of 9

What is the formula to convert Celsius to Fahrenheit?

Correct Answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is (C 9/5) + 32. This formula involves multiplying the Celsius temperature by 9/5 and then adding 32 to get the Fahrenheit temperature. Choice B is incorrect as it suggests dividing by 5/9 instead of multiplying by 9/5. Choices C and D are both incorrect because they involve using the Fahrenheit temperature in the calculation, which is not the correct method for converting Celsius to Fahrenheit.

Question 5 of 9

What is 0.45 liters in milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equivalent to 450 milliliters. Choice B, 45 ml, is incorrect as it represents the conversion of 0.045 liters to milliliters. Choice C, 4.5 ml, is incorrect as it represents the conversion of 0.0045 liters to milliliters. Choice D, 0.45 ml, is incorrect as it is the initial quantity in milliliters and not the result of the conversion.

Question 6 of 9

What is 0.5 liters converted to milliliters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.5 liters converts to 500 milliliters. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.

Question 7 of 9

Convert 3,540 liters to milliliters (mL).

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in 1 liter. Therefore, 3,540 liters 1,000 = 3,540,000 milliliters. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters. A, C, and D are off by a factor of 1,000, as they do not account for the conversion factor between liters and milliliters.

Question 8 of 9

How many pounds are in 1 ton?

Correct Answer: B

Rationale: The correct answer is B: 2000 pounds. A ton is equivalent to 2000 pounds. This is a standard conversion in the imperial system of measurement. Choice A, 1000 pounds, is incorrect as it represents half a ton. Choice C, 1500 pounds, and Choice D, 2500 pounds, are also incorrect as they do not match the correct conversion of 1 ton to 2000 pounds.

Question 9 of 9

What is the expression 1 in. = 2.54 cm properly called?

Correct Answer: D

Rationale: The correct answer is D: Exact Equivalent. The expression 1 inch = 2.54 cm is a direct and precise conversion between inches and centimeters, making it an exact equivalent. It is not related to the Law of Conservation of Units (A) as this principle pertains to the conservation of physical quantities in a system. The International Yard (B) is a unit of measurement, but it is not the term for the given expression. Similarly, while the conversion factor in the expression is standard, it is specifically an exact equivalent and not just a general standard conversion factor (C). Therefore, D is the most appropriate term to describe this specific conversion relationship.
