TEAS Test Sample Math Questions

Correct Answer: B

Rationale: To add 1/6 and 1/2, find a common denominator which is 6. Then, 1/6 + 1/2 = (1/6) + (3/6) = 4/6. Simplifying 4/6 gives 2/3, which is the reduced form of the sum. Choice B is correct. Choices A, C, and D are incorrect because they do not represent the correct result of adding 1/6 and 1/2 in reduced form. Option A simplifies to 9/7, Option C simplifies to 31/36, and Option D simplifies to 3/5, none of which are the correct answer.

Correct Answer: D

Rationale: To express 8 3/7 as an improper fraction, we multiply the whole number (8) by the denominator of the fraction (7), then add the numerator (3) to get the numerator of the improper fraction. So, 8 * 7 + 3 = 59. The denominator remains the same, so the improper fraction is 59/7. Explanation of other choices: A: 11/7 - Incorrect. This is the sum of the whole number and fraction as a mixed number, not an improper fraction. B: 21/8 - Incorrect. This doesn't represent 8 3/7 as an improper fraction. C: 5/3 - Incorrect. This is a completely different fraction and does not represent 8 3/7.

Correct Answer: A

Rationale: To solve the problem 6 + 3 * 2, we must follow the order of operations (PEMDAS/BODMAS). According to this rule, multiplication should be completed first before addition. So, 3 * 2 = 6. Then we add 6 to 6 to get the final answer of 12. Therefore, the correct operation to be completed first is multiplication (Choice A). The other choices are incorrect because division and subtraction are not part of the given equation, and addition should only be done after completing multiplication in this case.

Correct Answer: C

Rationale: To find the fraction of blue shirts, we must first determine the fraction of green and red shirts. Given that 2/5 are green and 1/3 are red, the remaining fraction for blue shirts can be calculated by subtracting the sum of green and red fractions from 1 (total). Green: 2/5, Red: 1/3 Total fraction of green and red shirts: 2/5 + 1/3 = 6/15 + 5/15 = 11/15 Fraction of blue shirts: 1 - 11/15 = 4/15 Therefore, the correct answer is C (7/15) as the fraction of blue shirts is 4/15, leaving 7/15 for blue shirts. Other choices are incorrect as they do not align with the calculated fraction for blue shirts.

Correct Answer: D

Rationale: To write 0.80 as a percent, you multiply it by 100. So, 0.80 * 100 = 80%. Therefore, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as 0.80 is less than 100%. Choice C (90%) is incorrect because 0.80 is not equal to 90%.
