Math Practice TEAS Test

Correct Answer: A

Rationale: To find the ratio of students with brown eyes to students with green eyes, we divide the number of students with brown eyes by the number of students with green eyes. In this case, 14 students with brown eyes divided by 2 students with green eyes equals 7. Therefore, the correct ratio is 7:1 (choice A). Choice B is incorrect as it represents the ratio of 7:2, which is the reverse of the given scenario. Choice C is incorrect as it shows the ratio of 14:2, which can be further simplified to 7:1. Choice D is incorrect as it incorrectly states the ratio as 14:1, which is not the case based on the information provided.

Correct Answer: B

Rationale: The correct answer is B (0.23). To find the percentage donated to support construction, we need to subtract the percentage that went towards construction costs from 100% (total). Therefore, 100% - 23% = 77%. This means that 77% of the funds were donated to support construction. Choice A (0.49), C (0.18), and D (0.1) are incorrect because they do not represent the correct percentage of funds donated to support construction after deducting the construction costs.

Correct Answer: A

Rationale: The correct answer is A: 2.54 centimeters in an inch; 0.393 inches in a centimeter. The conversion factor between inches and centimeters is 2.54, derived from the definition of an inch. To convert inches to centimeters, you multiply by 2.54. Conversely, to convert centimeters to inches, you divide by 2.54. The other choices are incorrect because they do not reflect the accurate conversion factor between inches and centimeters. B and C have incorrect conversion ratios, while D has an incorrect relationship between inches and centimeters.

Correct Answer: A

Rationale: The correct answer is A: y = 3x. To find the relationship between x and y, we can observe that y is always 3 times the value of x in each row. For example, when x = 2, y = 6 (6 = 3 * 2). This pattern holds true for all data points provided. Therefore, the correct equation is y = 3x. Choice B (x = 3y) is incorrect because it suggests that x is 3 times the value of y, which is not the case based on the given data. Choice C (y = x/3) is incorrect as it implies that y is one-third of x, which does not match the relationship shown in the table. Choice D (y = x + 3) is incorrect as it simply adds 3 to x to get y, which is not consistent with the provided data points.

Correct Answer: A

Rationale: The correct answer is A: Feet are larger; 1 foot is 0.3048 meters. To determine which is larger, we need to compare the conversion factor. 1 foot is equal to 0.3048 meters, indicating that a foot is smaller than a meter. Therefore, meters are larger than feet. Choice B is incorrect because 1 meter is equivalent to 3.28 feet, showing that a meter is larger. Choice C is incorrect as 1 foot is not 0.5 meters, and Choice D is incorrect as 1 meter is not 2 feet.
