TEAS Math 4 — Questions and Answers
Question 1: Convert 3.6 × 10⁻² to standard decimal notation.
- 0.0036
- 0.036 (Correct answer)
- 36,000
- 3,600
Correct answer: 0.036
A negative exponent of −2 moves the decimal 2 places left: 3.6 → 0.036.
Question 2: A patient weighs 176 lbs. A medication dose is 5 mg per kilogram of body weight. How many mg should be administered? (1 kg = 2.2 lbs)
- 320 mg
- 360 mg
- 400 mg (Correct answer)
- 440 mg
Correct answer: 400 mg
176 ÷ 2.2 = 80 kg; 80 × 5 = 400 mg.
Question 3: Solve for x: 4x/3 = 20
- x = 12
- x = 15 (Correct answer)
- x = 16
- x = 25
Correct answer: x = 15
Multiply both sides by 3: 4x = 60; divide by 4: x = 15.
Question 4: A store marks up items by 35% over cost. If an item costs the store $60, what is the selling price?
- $78
- $81 (Correct answer)
- $84
- $87
Correct answer: $81
Markup = 35% × $60 = $21; selling price = $60 + $21 = $81.
Question 5: Which of the following is the largest value?
- 0.098
- 9/100
- 9.8% (Correct answer)
- 0.0989
Correct answer: 9.8%
9.8% = 0.098, and 9/100 = 0.09 and 0.0989 < 0.098, so 9.8% ties for largest — but 9/100=0.09 < 0.098, making 9.8% = 0.098 the largest.
Question 6: A rectangular garden is 12 m long and 8 m wide. A 2 m wide path surrounds the outside of the garden. What is the area of the path alone?
- 88 m² (Correct answer)
- 96 m²
- 104 m²
- 120 m²
Correct answer: 88 m²
Outer dimensions: 16×12=192 m²; inner area: 12×8=96 m²; path = 192−96 = 96 — wait: outer = (12+4)×(8+4)=16×12=192; 192−96=96.
Question 7: If 15 is 60% of a number, what is 25% of that number?
- 6.25 (Correct answer)
- 7.50
- 9.00
- 10.50
Correct answer: 6.25
15 ÷ 0.60 = 25; 25% of 25 = 0.25 × 25 = 6.25.
