1. 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.

2. How many milliliters are in a tablespoon?

• A. 10 ml
• B. 15 ml
• C. 5 ml
• D. 20 ml

Correct answer: B

Rationale: The correct answer is B: 15 ml. One tablespoon is equivalent to 15 milliliters. The conversion factor for tablespoons to milliliters is 1 tablespoon = 15 milliliters. Choice A (10 ml) is incorrect because it is not the standard conversion for a tablespoon. Choice C (5 ml) is incorrect as it is too low for a tablespoon. Choice D (20 ml) is incorrect as it is too high for a tablespoon. Therefore, the correct conversion is 15 milliliters for one tablespoon.

3. Convert 5 kilograms to grams.

• A. 50 grams
• B. 500 grams
• C. 5,000 grams
• D. 50,000 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 5 kilograms is equal to 5,000 grams. Choices A, B, and D are incorrect because they do not correctly convert the given amount of kilograms to grams.

4. What does 'm' stand for in the metric system?

• A. meter
• B. mole
• C. milli
• D. micro

Correct answer: A

Rationale: The correct answer is 'meter.' In the metric system, 'm' stands for meter, which is the base unit for length. Choice B, 'mole,' is a unit used in chemistry to represent an amount of substance. Choice C, 'milli,' represents a prefix indicating one-thousandth, and choice D, 'micro,' represents a prefix indicating one-millionth. Therefore, the correct choice is 'A: meter.'

5. What is 0.45 liters in milliliters?

• A. 450 ml
• B. 45 ml
• C. 4.5 ml
• D. 0.45 ml

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.
