Metric Conversions for TEAS 7

Correct Answer: C

Rationale: The correct answer is C: 1,000 grams. There are 1,000 grams in 1 kilogram because the prefix "kilo-" in the metric system signifies 1,000. Therefore, 1 kilogram equals 1,000 grams. Choice A (10 grams) is incorrect because it is not equivalent to a kilogram. Choice B (100 grams) is incorrect as well, as it is also not the correct conversion. Choice D (10,000 grams) is incorrect because it is ten times the amount in a kilogram.

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we need to write it as 7/100 since 0.07 is equivalent to 7/100 in fraction form. The correct answer is A (7/100). Choice B (7/50) is incorrect because 0.07 is not equivalent to 7/50. Choice C (7/25) is incorrect as well since it does not represent 0.07. Choice D (7/10) is incorrect because 0.07 is not equal to 7/10. The closest fraction to 0.07 is 7/100, making it the correct answer.

Correct Answer: C

Rationale: To convert kilograms to grams, we need to multiply the number of kilograms by 1000 since there are 1000 grams in 1 kilogram. Therefore, to find out how many grams are in 5 kilograms, we multiply 5 by 1000, which equals 5000 grams. The correct answer is C. A: 50 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 50 grams. B: 500 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 500 grams. D: 5 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 5 grams.

Correct Answer: B

Rationale: The correct answer is B: 2 cups in one pint. A pint is equivalent to 2 cups in the US customary system of measurement. This conversion is based on the fact that 1 pint is equal to 16 fluid ounces, and 1 cup is equal to 8 fluid ounces. Therefore, 16 fluid ounces (1 pint) divided by 8 fluid ounces (1 cup) equals 2 cups. The other choices are incorrect because they do not accurately represent the conversion between pints and cups. Choice A (1 cup) is incorrect as it does not match the conversion factor. Choices C (3 cups) and D (4 cups) are incorrect as they provide values that do not align with the correct measurement relationship between pints and cups.

Correct Answer: D

Rationale: The correct answer is D: 1000 milliliters. 1 liter is equivalent to 1000 milliliters. This is because the metric system is based on the powers of 10, so there are 1000 milliliters in 1 liter. Choice A, 1 kilogram, is a unit of mass and not volume. Choice B, 1 quart, is a unit of volume but is not equivalent to 1 liter. Choice C, 1 milliliter, is much smaller than 1 liter, as it would take 1000 milliliters to make up 1 liter.
