TEAS Practice Test Math

Correct Answer: A

Rationale: To determine the amount of yogurt, we first find the total parts in the ratio (4+3=7 parts). Since toppings are 3 parts, we divide 4.5 oz by 3 to find 1 part equals 1.5 oz. Then, multiply 1.5 oz by 4 (yogurt parts) to get 6 oz of yogurt. Choice A is correct because it correctly calculates the amount of yogurt based on the given ratio. Choices B, C, and D are incorrect as they do not follow the correct calculation based on the ratio provided.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Jacob spends 87% of $100 = $87, leaving her with $13. 2. She invests $13 and earns a profit of 75%. 3. 75% of $13 = $9.75 profit. 4. Adding the profit to the remaining amount: $13 + $9.75 = $22.75. Therefore, Jacob now has $22.75. Summary of other choices: A: $13.00 - Incorrect, as this is the remaining amount before the investment. B: $87.00 - Incorrect, this is the amount Jacob initially spent. D: $9.75 - Incorrect, this is the profit earned from the investment, not the total amount Jacob now has.

Correct Answer: B

Rationale: To find the number of students in the respiratory care program, we need to calculate the percentage of students in that program based on the pie chart. The respiratory care program occupies 19% of the pie chart. 19% of 800 students is 0.19 * 800 = 152. Therefore, the correct answer is B: 152. Choice A (336) is incorrect as it represents the percentage of students in a different program, not respiratory care. Choice C (144) and Choice D (168) are also incorrect as they do not correspond to the percentage allocated for the respiratory care program in the pie chart.

Correct Answer: A

Rationale: To convert yards to feet, you multiply by 3 because there are 3 feet in 1 yard. To convert feet to yards, you divide by 3. So, the correct answer is A. For the other choices, B, C, and D, the conversion factors are incorrect and do not match the actual relationship between yards and feet. B and D have incorrect multiplication factors, while C has an incorrect multiplication factor and division factor.

Correct Answer: D

Rationale: To compare the values, convert them to the same format. Convert 2/11 to a decimal (0.1818), 13/3 to a decimal (4.33), and 6.25 remains unchanged. Now, it's clear that 6.25 is the greatest value as it is larger than both 0.1818 and 4.33. Option B (5.4) is also smaller than 6.25. Thus, the correct answer is D.
