Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: Inches are larger. This is because one inch is equivalent to 2.54 centimeters. Therefore, when comparing the two units, inches are larger in size. Centimeters are smaller units of measurement compared to inches. Choice B is incorrect as centimeters are smaller. Choice C is incorrect because they are not the same size. Choice D is incorrect as the relationship between inches and centimeters is fixed with 1 inch being larger than 1 centimeter.

Correct Answer: B

Rationale: The correct answer is B: Low positive correlation. This is because the data shows a general increasing trend, but the points are scattered and do not form a tight linear relationship. The correlation coefficient would be closer to 0 than to +1, indicating a weak positive correlation. Choices A and C are incorrect as they suggest stronger correlations, which is not supported by the data. Choice D is incorrect as there is some level of relationship between the variables, even if it is weak.

Correct Answer: A

Rationale: The correct answer is A: Mile is bigger; 1 mile is 1.609 km. This is because a mile is a longer unit of measurement compared to a kilometer. The conversion factor is 1 mile equals 1.609 kilometers. To convert miles to kilometers, you multiply the number of miles by 1.609. The other choices are incorrect because: B: Kilometer is bigger; 1 km is 1.609 miles - This is incorrect as a kilometer is shorter than a mile. C: Mile is bigger; 1 mile is 1.5 km - This is incorrect as 1 mile is actually equal to about 1.609 kilometers. D: Kilometer is bigger; 1 km is 2 miles - This is incorrect as a kilometer is shorter than 2 miles.

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we calculate the multiplication and division from left to right: 6 + 7 = 13, 13 - 4 = 9, 9 * 2 = 18. So, the correct answer is 18. Choice A is incorrect because it is the result of multiplying all the numbers together. Choice C is incorrect as it is the result of adding all the numbers together. Choice D is incorrect as it is the result of adding the first two numbers and then multiplying by the last two numbers.

Correct Answer: C

Rationale: To arrange fractions from least to greatest, find a common denominator. For 2/3, 1/2, 5/8, 7/9, the common denominator is 72. Convert each fraction: 2/3 = 24/72, 1/2 = 36/72, 5/8 = 45/72, 7/9 = 56/72. Now, arrange them: 24/72, 36/72, 45/72, 56/72. Thus, the correct order is 1/2, 5/8, 2/3, 7/9 (Choice C). Other choices are incorrect because they do not follow the correct order after converting to a common denominator.
