1. What is 0.5 liters in 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 equals 500 milliliters. This conversion is commonly used in various fields such as cooking, medicine, and science. Choice B, 50 ml, is incorrect as it represents 0.05 liters, not 0.5 liters. Choice C, 5 ml, is even smaller and represents 0.005 liters. Choice D, 0.5 ml, is incorrect as it is a tenth of the correct conversion.

2. What is 0.04 g in mg?

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

Correct answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. Therefore, to convert 0.04 grams to milligrams, you would do 0.04 * 1000 = 40 mg. Choice A, '40 mg,' is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert grams to milligrams. Choice B, '400 mg,' is incorrect because it mistakenly multiplies by 10 instead of 1000. Choice C, '4 mg,' is incorrect because it does not account for the correct conversion factor. Choice D, '0.4 mg,' is incorrect because it underestimates the conversion by a factor of 10.

3. Convert 0.5 centimeters to millimeters.

• A. 5 mm
• B. 0.5 mm
• C. 50 mm
• D. 0.05 mm

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.

4. What is 0.875 as a simplified fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.

5. Convert 0.07 to a fraction.

• A. 7/100
• B. 1/10
• C. 1/20
• D. 1/50

Correct answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 is equivalent to 7/100. This is because 0.07 can be read as 7 hundredths. Thus, the correct fraction form is 7/100. Choices B, C, and D are incorrect. Choice B, 1/10, is the fraction equivalent to 0.1, not 0.07. Choice C, 1/20, and Choice D, 1/50, are also incorrect as they do not represent the value of 0.07 when converted to a fraction.
