Metric Conversions for TEAS 7 Questions

Question 1 of 5

How many millimeters are in 0.75 centimeters?

Correct Answer: C

Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.

Question 2 of 5

Convert 345 kilometers to meters (m).

Correct Answer: B

Rationale: To convert kilometers to meters, you multiply by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 345 kilometers x 1000 = 345,000 meters. Choice A is incorrect as it doesn't account for the conversion factor. Choice C is incorrect as it adds an extra zero. Choice D is incorrect as it adds two extra zeros. Choice B is the correct answer as it correctly converts 345 kilometers to meters by multiplying by 1000.

Question 3 of 5

How many centimeters are in 1 meter?

Correct Answer: B

Rationale: The correct answer is B: 100 cm. There are 100 centimeters in 1 meter because the metric system is based on units of 10. 1 meter is equivalent to 100 centimeters as each meter is divided into 100 equal parts, which are centimeters. Choice A (10 cm) is incorrect as it represents the number of millimeters in a centimeter. Choice C (1,000 cm) is incorrect as it represents the number of millimeters in a meter. Choice D (10,000 cm) is incorrect as it is ten times the actual number of centimeters in a meter.

Question 4 of 5

How many milliliters are in 0.5 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. So, to find how many milliliters are in 0.5 liters, you multiply 0.5 by 1000, which equals 500 milliliters. Therefore, the correct answer is B: 500 mL. Choice A (50 mL) is incorrect because it is 10 times less than the correct answer. Choice C (5,000 mL) is incorrect because it is 10 times more than the correct answer. Choice D (5 mL) is incorrect because it is 100 times less than the correct answer.

Question 5 of 5

How many milliliters are there in 0.5 liters?

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter is equal to 1000 milliliters. So, 0.5 liters x 1000 = 500 milliliters. Therefore, the correct answer is A: 500 milliliters. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters. B is too small, C is even smaller, and D is a decimal value that does not represent a proper conversion.
