TEAS Math Practice Test

Correct Answer: B

Rationale: To convert 1.25 to a fraction, we note that the decimal has two decimal places. To convert it to a fraction, we write 1.25 as 125/100. Simplifying by dividing both numerator and denominator by 25, we get 5/4. Therefore, the correct answer is B: 5/4. A: 1 1/4 is the mixed number form of 5/4. C: 4/5 is the reciprocal of the correct answer. D: 25/20 is not simplified; it should be reduced to 5/4.

Correct Answer: C

Rationale: To find the sixth number, we can first calculate the sum of all six numbers by multiplying the average (6) by the total count (6), which equals 36. Since the sum of five numbers is 25, the sixth number can be found by subtracting 25 from 36, giving us 11 (Choice C). Other choices are incorrect because they do not satisfy the conditions given in the question. Choice A, 8, would make the sum of six numbers less than 36. Choice B, 10, would also make the sum less than 36. Choice D, 12, would make the sum greater than 36. Thus, the correct answer is C (11).

Correct Answer: A

Rationale: The correct answer is A: 75 dollars per gigabyte. The slope of the equation represents the rate of change in cost per unit change in data usage. In this case, for every additional gigabyte of data used (D), the cost of the phone bill (C) increases by $75. This interpretation aligns with the equation C = 50 + 75D, where 75 is the coefficient of D, indicating the cost per gigabyte. Summary of other choices: B: 75 gigabytes per day - This is incorrect as it does not reflect the cost per gigabyte relationship in the equation. C: 50 dollars per day - This is incorrect as it does not account for the cost associated with data usage. D: 50 dollars per gigabyte - This is incorrect because the correct cost per gigabyte is $75, not $50.

Correct Answer: A

Rationale: To convert 3 5/7 to an improper fraction, multiply the whole number (3) by the denominator (7) and add the numerator (5) to get 26. The denominator remains the same, resulting in 26/7. This is the correct answer because it represents the mixed number 3 5/7 in fraction form. Choice B (21/7) simplifies to 3, which is the whole number part of the mixed number. Choice C (22/7) is equivalent to the approximation of π and not the correct conversion of 3 5/7. Choice D (26/5) is incorrect as it does not represent the mixed number 3 5/7 accurately.
