Question 1: A rope is cut into pieces of 2.5 feet each. If the original rope is 17.5 feet long, how many pieces are cut?
- 7 (Correct answer)
- 6
- 8
- 5
Correct answer: 7
17.5 ÷ 2.5 = 7 pieces.
Question 2: What is 15% of 320?
- 48 (Correct answer)
- 42

Correct answer: 48
15% × 320 = 0.15 × 320 = 48.
Question 3: Which fraction is equivalent to 0.625?
- 5/8 (Correct answer)
- 3/5
- 7/10
- 5/6
Correct answer: 5/8
0.625 = 625/1000, which simplifies to 5/8.
Question 4: A tank holds 450 gallons. If 1/3 of the tank is used, how many gallons remain?
- 300 gallons (Correct answer)
- 150 gallons
- 225 gallons
- 350 gallons
Correct answer: 300 gallons
1/3 of 450 = 150 used, so 450 − 150 = 300 gallons remain.
Question 5: What is the absolute value of −18?
- 18 (Correct answer)
- −18
- 0
- 1/18
Correct answer: 18
The absolute value represents the distance from zero, so |−18| = 18.
Question 6: If 7x = 56, what is the value of x?
- 8 (Correct answer)
- 7
- 9
- 6
Correct answer: 8
Dividing both sides by 7 gives x = 56 ÷ 7 = 8.
