MPT Pre-Algebra 1 — Questions and Answers
Question 1: What is 12 ÷ 3?
- 3
- 4 (Correct answer)
- 5
- 6
Correct answer: 4
Division is a basic arithmetic operation that involves splitting a number into equal parts. When you divide 12 by 3, you are determining how many groups of 3 can be made from 12. The result is 4, because 3 multiplied by 4 equals 12.
Question 2: Which of the following is equivalent to 3/4 × 8/9?
- 24/36
- 1/3
- 2/3 (Correct answer)
- 3/2
Correct answer: 2/3
To multiply fractions, you multiply the numerators together and the denominators together. So, (3/4) × (8/9) = (3 × 8) / (4 × 9) = 24/36. This fraction can then be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 12, resulting in 2/3.
Question 3: What is the result of 25% of 200?
- 50 (Correct answer)
- 25
- 75
- 100
Correct answer: 50
25% of 200 is calculated by multiplying 200 by 0.25 (since 25% = 0.25). <br> 200 × 0.25 = 50.
Question 4: Solve for x: 5x = 25
- 5 (Correct answer)
- 4
- 3
- 6
Correct answer: 5
To solve for x, divide both sides of the equation by 5. <br> 5x ÷ 5 = 25 ÷ 5, so x = 5.
Question 5: What is the value of 3/5 + 2/5?
- 5/5
- 1 (Correct answer)
- 4/5
- 3/10
Correct answer: 1
When adding fractions with the same denominator, simply add the numerators. <br> 3/5 + 2/5 = (3 + 2)/5 = 5/5 = 1.
