TEAS Test Math Prep Questions
Question 1 of 5
The value of 6 x 12 is the same as:
Correct Answer: A
Rationale: The correct answer is A: 2 x 4 x 4 x 2. To find the value of 6 x 12, we can break it down into simpler multiplication. 6 x 12 = 6 x (4 x 3) = (2 x 3) x (4 x 3) = 2 x 4 x 4 x 2. This shows that the value of 6 x 12 is indeed equal to 2 x 4 x 4 x 2. Explanation for why other choices are incorrect: B: 7 x 4 x 3 does not equal 6 x 12. C: 6 x 6 x 3 equals 108, not 72 (6 x 12). D: 3 x 3 x 4 x 2 equals 72, but the order of multiplication is not the same as in 6 x 12, making it incorrect.
Question 2 of 5
You measure the width of your door to be 36 inches. The true width of the door is 75 inches. What is the relative error in your measurement?
Correct Answer: A
Rationale: To calculate relative error, we use the formula: (|Measured Value - True Value| / True Value) * 100%. In this case, the measured width is 36 inches and the true width is 75 inches. So, the relative error = (|36 - 75| / 75) * 100% = (39 / 75) * 100% = 52%. Therefore, the correct answer is A: 0.52%. Choice B (0.01%), C (0.99%), and D (0.10%) are incorrect as they do not correspond to the calculated relative error of 52% in this scenario.
Question 3 of 5
A student gets an 85% on a test with 20 questions. How many answers did the student solve correctly?
Correct Answer: C
Rationale: To determine how many questions the student answered correctly, we can calculate 85% of 20. 85% of 20 = 0.85 * 20 = 17. Therefore, the student answered 17 questions correctly. Option A, B, and D are incorrect because they do not correspond to the calculated result. Option A is too low, B is close but still lower, and D is too high.
Question 4 of 5
Simplify the following expression: 5/9 15/36
Correct Answer: A
Rationale: To simplify the expression 5/9 * 15/36, we first multiply the numerators (5 * 15 = 75) and the denominators (9 * 36 = 324) separately. This gives us 75/324. To simplify further, we find the greatest common divisor of 75 and 324, which is 3. Dividing both the numerator and denominator by 3, we get 25/108. Finally, this can be reduced to 5/36 by dividing both the numerator and denominator by 5. Therefore, the correct answer is A: 5/36. Choices B, C, and D are incorrect because they do not result from the correct simplification steps outlined above.
Question 5 of 5
Bernard can make $80 per day. If he needs to make $300 and only works full days, how many days will this take?
Correct Answer: C
Rationale: To reach $300, Bernard needs to work for $300 / $80 = 3.75 days. Since he can only work full days, he needs to work for 4 days to make at least $300. Thus, the correct answer is C. Option A (2 days), B (3 days), and D (5 days) are incorrect as they do not meet the minimum requirement of $300.
