TEAS Practice Test Math

Correct Answer: A

Rationale: To solve the equation 3(x-2) = 12 for x: 1. Distribute the 3 to both terms inside the parentheses: 3x - 6 = 12 2. Add 6 to both sides: 3x = 18 3. Divide by 3: x = 6 Choice A (6) is correct. Choice B (-2) results in x = 4, not 6. Choice C (-4) results in x = 2, not 6. Choice D (2) results in x = 8, not 6.

Correct Answer: B

Correct Answer: C

Rationale: To find the amount of sugar needed for 0.625 of the recipe, you multiply 0.375 (original amount) by 0.625 (desired portion). 0.375 x 0.625 = 0.234375 cups. Therefore, you should use 0.234375 cups of sugar. Choice A is incorrect as it adds the original and desired portions. Choice B is close but not the correct calculation. Choice D is way off, likely a miscalculation.

Correct Answer: B

Correct Answer: B

Rationale: To find the ratio of girls to boys, we divide the number of girls by the number of boys. In this case, there are 26 girls and 22 boys. So, the ratio of girls to boys is 26:22, which simplifies to 13:11. Therefore, choice B (13:11) is the correct answer. Choice A (26:11) is incorrect because it incorrectly combines the total number of girls with the number of boys. Choice C (13:22) is incorrect because it reverses the order of girls and boys in the ratio. Choice D (11:13) is incorrect because it flips the ratio of girls to boys.
