Q: A car travels 240 miles in 4 hours. What is its average speed in miles per hour?
A: 60 mph. Speed = Distance ÷ Time = 240 ÷ 4 = 60 mph
Q: If 25% of a number is 80, what is the number?
A: 320. Let x be the number. 0.25x = 80, so x = 80 ÷ 0.25 = 320
Q: What is 3/4 + 2/3?
A: Find a common denominator: (3/4 = 9/12), (2/3 = 8/12), so 9/12 + 8/12 = 17/12 or 1 5/12
Q: Solve for x: 3x + 7 = 22
A: x = 5. Subtract 7 from both sides: 3x = 15, then divide by 3: x = 5
Q: What is the area of a rectangle with length 12 feet and width 8 feet?
A: 96 square feet. Area = length × width = 12 × 8 = 96 sq ft
Q: A shirt costs $45 and is on sale for 20% off. What is the sale price?
A: $36. Discount = $45 × 0.20 = $9. Sale price = $45 - $9 = $36
Q: If 5 workers can complete a job in 8 hours, how long will it take 10 workers?
A: 4 hours. Total work = 5 × 8 = 40 worker-hours. Time = 40 ÷ 10 = 4 hours
Q: What is 0.75 as a fraction in lowest terms?
A: 3/4. 0.75 = 75/100 = 3/4 (divide numerator and denominator by 25)
Q: The perimeter of a square is 36 inches. What is its area?
A: 81 square inches. Side length = 36 ÷ 4 = 9 inches. Area = 9² = 81 sq in
Q: A train travels 180 miles in 3 hours. At this rate, how far will it travel in 5 hours?
A: 300 miles. Speed = 180 ÷ 3 = 60 mph. Distance = 60 × 5 = 300 miles
Q: What is 40% of 250?
A: 100. 40% of 250 = 0.40 × 250 = 100
Q: Solve: 2x - 5 = 11
A: x = 8. Add 5 to both sides: 2x = 16, then divide by 2: x = 8
Q: What is the circumference of a circle with radius 7 inches? (Use π = 3.14)
A: 43.96 inches. Circumference = 2πr = 2 × 3.14 × 7 = 43.96 inches
Q: A recipe calls for 2 1/4 cups of flour. How much flour is needed for 3 recipes?
A: 6 3/4 cups. 2 1/4 × 3 = 9/4 × 3 = 27/4 = 6 3/4 cups
Q: What is 2³ × 3²?
A: 72. 2³ = 8 and 3² = 9, so 8 × 9 = 72
Q: A right triangle has legs of 3 and 4 units. What is the length of the hypotenuse?
A: 5 units. Using Pythagorean theorem: c² = 3² + 4² = 9 + 16 = 25, so c = 5
Q: If a gallon of paint covers 350 square feet, how many gallons are needed for 1,050 square feet?
A: 3 gallons. 1,050 ÷ 350 = 3 gallons
Q: What is 15% of 120?
A: 18. 15% of 120 = 0.15 × 120 = 18
Q: A box contains 24 apples. If 1/3 are red and the rest are green, how many are green?
A: 16 apples. Red apples = 24 × 1/3 = 8. Green apples = 24 - 8 = 16
Q: What is the volume of a cube with side length 4 inches?
A: 64 cubic inches. Volume = side³ = 4³ = 64 cubic inches
Q: A bicycle wheel has a diameter of 26 inches. What is its radius?
A: 13 inches. Radius = diameter ÷ 2 = 26 ÷ 2 = 13 inches
Q: If x + 12 = 20, what is x?
A: x = 8. Subtract 12 from both sides: x = 20 - 12 = 8
Q: What is 7/8 - 1/2?
A: 3/8. Convert to common denominator: 7/8 - 4/8 = 3/8
Q: A store sells 480 items in 8 hours. What is the average number of items sold per hour?
A: 60 items per hour. 480 ÷ 8 = 60 items per hour
