TEAS Math Practice Test #3 3 — Questions and Answers
Question 1: Solve for y: 2y − 5 = 3y + 4
- y = −9 (Correct answer)
- y = −1
- y = 1
- y = 9
Correct answer: y = −9
Subtract 2y from both sides: −5 = y + 4. Subtract 4 from both sides: y = −9. Check: 2(−9)−5 = −18−5 = −23; 3(−9)+4 = −27+4 = −23. ✓
Question 2: A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. What is the probability of randomly selecting a blue marble?
- 1/5
- 3/10 (Correct answer)
- 3/7
- 1/3
Correct answer: 3/10
Total marbles: 5+3+2 = 10. Blue marbles: 3. Probability = 3/10.
Question 3: What is the volume of a rectangular box with length 6 cm, width 4 cm, and height 3 cm?
- 36 cm³
- 48 cm³
- 60 cm³
- 72 cm³ (Correct answer)
Correct answer: 72 cm³
Volume = length × width × height = 6 × 4 × 3 = 72 cm³.
Question 4: A nurse must administer 45 mg of medication. The available dose is 15 mg per tablet. How many tablets are needed?
- 2
- 3 (Correct answer)
- 4
- 5
Correct answer: 3
Number of tablets = desired dose ÷ dose per tablet = 45 ÷ 15 = 3 tablets.
Question 5: Which of the following represents the ratio 18:27 in simplest form?
- 3:4
- 2:3 (Correct answer)
- 6:9
- 9:13
Correct answer: 2:3
Find the GCF of 18 and 27: GCF = 9. Divide both by 9: 18/9 = 2, 27/9 = 3. Simplest form: 2:3.
Question 6: A student scored 84 out of 120 on a test. What percentage did they score?
- 60%
- 65%
- 70% (Correct answer)
- 75%
Correct answer: 70%
Percentage = (score/total) × 100 = (84/120) × 100 = 0.70 × 100 = 70%.
