GED Math Test #5 3 — Questions and Answers
Question 1: What is 35% of 260?
- 91 (Correct answer)
- 84
- 78
- 96
Correct answer: 91
35% of 260 = 0.35 × 260 = 91. To find a percentage of a number, convert the percent to a decimal and multiply.
Question 2: A rectangle has a length of 14 cm and a width of 9 cm. What is its area?
- 126 cm² (Correct answer)
- 46 cm²
- 112 cm²
- 136 cm²
Correct answer: 126 cm²
Area of a rectangle = length × width = 14 × 9 = 126 cm². The perimeter would be 2(14 + 9) = 46 cm, which is a common distractor.
Question 3: Solve for x: 3x + 7 = 28
- 7 (Correct answer)
- 6
- 9
- 5
Correct answer: 7
Subtract 7 from both sides: 3x = 21. Then divide by 3: x = 7. Always perform inverse operations to isolate the variable.
Question 4: A store sold 48 items on Monday and 72 items on Tuesday. What fraction of the two-day total was sold on Monday?
- 2/5 (Correct answer)
- 1/3
- 3/5
- 2/3
Correct answer: 2/5
Total items = 48 + 72 = 120. Monday fraction = 48/120 = 2/5. Simplify by dividing numerator and denominator by their GCF of 24.
Question 5: The table shows: x = 2 → y = 5; x = 4 → y = 9; x = 6 → y = 13. Which equation represents this relationship?
- y = 2x + 1 (Correct answer)
- y = 3x − 1
- y = x + 3
- y = 2x − 1
Correct answer: y = 2x + 1
Check with x = 2: 2(2) + 1 = 5 ✓; x = 4: 2(4) + 1 = 9 ✓; x = 6: 2(6) + 1 = 13 ✓. The slope is (9−5)/(4−2) = 2 and the y-intercept is 1.
Question 6: A car travels 180 miles in 3 hours. At the same rate, how far will it travel in 5 hours?
- 300 miles (Correct answer)
- 270 miles
- 360 miles
- 240 miles
Correct answer: 300 miles
Rate = 180 ÷ 3 = 60 mph. Distance in 5 hours = 60 × 5 = 300 miles. Use the formula distance = rate × time.
