Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is the metric equivalent of 1 inch?
Correct Answer: B
Rationale: The correct answer is B: 2.54 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. This conversion factor is based on the definition of an inch and a centimeter. Therefore, 1 inch is equivalent to 2.54 centimeters. Choice A (1.54 cm) is incorrect as it is not the correct conversion factor for inches to centimeters. Choice C (3.54 cm) and Choice D (4.54 cm) are also incorrect as they do not correspond to the accurate conversion of inches to centimeters.
Question 2 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 3 of 5
What is 0.875 as a fraction?
Correct Answer: A
Rationale: To convert 0.875 to a fraction, we can write it as 875/1000 and simplify it to 7/8 by dividing both the numerator and denominator by 125. The correct answer is A (7/8). Choice B (9/10) is incorrect as it does not represent 0.875. Choices C (5/6) and D (3/4) are also incorrect fractions as they do not equal 0.875 when converted.
