Metric Conversions for TEAS 7
1. What is 0.1 liter converted to milliliters?
- A. 10 ml
- B. 100 ml
- C. 1000 ml
- D. 1 ml
Correct answer: B
Rationale: To convert 0.1 liter to milliliters, you need to multiply by 1000 because there are 1000 milliliters in a liter. Therefore, 0.1 liter converts to 100 milliliters. Choice A (10 ml) is incorrect as it represents 0.01 liters, not 0.1 liters. Choice C (1000 ml) is incorrect as it represents 1 liter, not 0.1 liters. Choice D (1 ml) is incorrect as it is too small a quantity for 0.1 liters.
2. Convert 0.2 liters to milliliters.
- A. 20 ml
- B. 200 ml
- C. 2 ml
- D. 2000 ml
Correct answer: B
Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.2 liters x 1000 = 200 ml. Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.
3. What is the base unit for volume of a solid in the metric system?
- A. cubic meters
- B. meters cubed
- C. grams
- D. centimeters
Correct answer: A
Rationale: The correct answer is 'cubic meters' (A) which is the base unit for volume of a solid in the metric system. Volume is measured in cubic units (length × width × height) for solids. Choice B, 'meters cubed,' is not the standard way to express volume in the metric system. Choices C and D, 'grams' and 'centimeters,' are units of mass and length respectively, not volume.
4. What is 0.004 as a simplified ratio?
- A. 1:250
- B. 4:35
- C. 7:28
- D. 4:00
Correct answer: A
Rationale: To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250. Choice B, 4:35, is incorrect as it does not reflect the correct conversion. Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004. Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.
5. How many ounces are in 2 quarts?
- A. 8 ounces
- B. 32 ounces
- C. 16 ounces
- D. 64 ounces
Correct answer: C
Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.
