GED - General Educational Development Mathematical Reasoning Arithmetic and Number Sense 1 — Questions and Answers
Question 1: A recipe calls for 2/3 cup of sugar to make one batch of cookies. How many cups of sugar are needed to make 4 batches?
- 2 1/3 cups
- 2 2/3 cups (Correct answer)
- 3 cups
- 1 2/3 cups
Correct answer: 2 2/3 cups
Multiply 2/3 by 4: (2/3) × 4 = 8/3. Converting to a mixed number: 8 ÷ 3 = 2 remainder 2, so 8/3 = 2 2/3 cups.
Question 2: Which of the following is equivalent to 5/8 expressed as a percent?
- 58%
- 56.25%
- 62.5% (Correct answer)
- 0.625%
Correct answer: 62.5%
Divide 5 by 8 to get the decimal: 5 ÷ 8 = 0.625. Multiply by 100 to convert to a percent: 0.625 × 100 = 62.5%.
Question 3: A jacket originally priced at $80 is on sale for 35% off. What is the sale price?
- $28.00
- $45.00
- $48.00
- $52.00 (Correct answer)
Correct answer: $52.00
Find the discount: 35% of $80 = 0.35 × 80 = $28. Subtract from the original price: $80 − $28 = $52.
Question 4: What is the value of −6 + (−4) − (−10)?
- 0 (Correct answer)
- −20
- 20
- −12
Correct answer: 0
Subtracting a negative is the same as adding a positive: −6 + (−4) − (−10) = −6 − 4 + 10 = −10 + 10 = 0.
Question 5: A car travels 180 miles in 3 hours. At the same speed, how far will it travel in 5 hours?
- 270 miles
- 300 miles (Correct answer)
- 250 miles
- 360 miles
Correct answer: 300 miles
Find the speed: 180 ÷ 3 = 60 miles per hour. Then multiply by 5 hours: 60 × 5 = 300 miles.
Question 6: Which of the following correctly orders −2, 3/4, −0.5, 1, and −1/4 from greatest to least?
- 1, 3/4, −1/4, −0.5, −2 (Correct answer)
- −2, −0.5, −1/4, 3/4, 1
- 1, 3/4, −0.5, −1/4, −2
- 3/4, 1, −1/4, −2, −0.5
Correct answer: 1, 3/4, −1/4, −0.5, −2
Converting to decimals: 1 = 1.0, 3/4 = 0.75, −1/4 = −0.25, −0.5, −2. From greatest to least: 1, 0.75, −0.25, −0.5, −2, which is 1, 3/4, −1/4, −0.5, −2.
