TEAS Exam Math Practice Questions
Question 1 of 5
Which of the following is equivalent to 3.28?
Correct Answer: D
Rationale: To convert a decimal to a fraction, we count the number of decimal places and put the digits after the decimal over the appropriate power of 10. For 3.28, there are two decimal places, so we write it as 328/100. Simplifying gives us 41/25, which matches choice D. Choices A, B, and C are incorrect as they do not represent the value of 3.28 when converted to a fraction. Option A is equivalent to 3.28 written as 3.28/1, which is not correct. Options B and C do not represent 3.28 accurately either.
Question 2 of 5
What is the result of (4.71 10^3) - (2.98 10^2)? Which of the following is the correct simplified expression?
Correct Answer: D
Rationale: To subtract numbers in scientific notation, we need to ensure the exponents are the same. First, convert 2.98 x 10^2 to 0.298 x 10^3. Then, subtract 4.71 x 10^3 - 0.298 x 10^3 = 4.412 x 10^3. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the correct result of the subtraction operation.
Question 3 of 5
Simplify the expression. What is the value of x? (5/4)x = 20
Correct Answer: D
Rationale: To solve the equation (5/4)x = 20, we first multiply both sides by 4/5 to isolate x. So, x = 20 * 4/5 = 16. Therefore, the correct answer is D. Option A, 8, is incorrect because x is not equal to 8. Option B, 24, and option C, 32, are also incorrect as they do not satisfy the given equation.
Question 4 of 5
Anna is buying fruit at the farmers' market. She selects 1.2 kilograms of apples, 800 grams of bananas, and 300 grams of strawberries. The farmer charges her a flat rate of $4 per kilogram. What is the total cost of her produce?
Correct Answer: C
Rationale: To calculate the total cost: 1. Convert all weights to kilograms: - Apples: 1.2 kg - Bananas: 0.8 kg - Strawberries: 0.3 kg 2. Calculate the total weight: 1.2 + 0.8 + 0.3 = 2.3 kg 3. Multiply total weight by the flat rate: 2.3 kg x $4/kg = $9.20 Therefore, the correct answer is C: $9.20. Other choices are incorrect because they do not follow the correct calculation based on the flat rate per kilogram.
Question 5 of 5
Which of the following lists is in order from least to greatest? (1/7), 0.125, (6/9), 0.60
Correct Answer: C
Rationale: To determine the correct order from least to greatest, convert all fractions to decimals: - (1/7) = 0.142857 - 0.125 - (6/9) = 0.666666 - 0.60 The correct order is 0.125, (1/7), 0.60, (6/9) because 0.125 is the smallest, followed by (1/7), then 0.60, and finally (6/9) which is equivalent to 0.666666. Other choices are incorrect because they do not follow the increasing order of magnitude. Choice A has the fractions in a different order, choice B has 0.60 in the wrong position, and choice D has the fractions in the wrong order. Therefore, choice C is the correct answer.
