1. Which number is greater than 6,331

Correct Answer: Correct answer is: (B) 6,430.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Very Easy

Concept notes: The question asks for a number greater than 6,331. We need to compare each option with 6,331 to determine which one is greater.

Common Mistakes: A common mistake would be to overlook the comparison and choose an option that is not greater than 6,331.

Explanations: To determine which number is greater than 6,331, we compare each option: - 5,326 is less than 6,331. - 6,430 is greater than 6,331. - 6,330 is less than 6,331. - 5,452 is less than 6,331. Thus, the only number greater than 6,331 is 6,430.

Option Analysis:

Option A: 5,326 is less than 6,331.
Option B: 6,430 is greater than 6,331.
Option C: 6,330 is less than 6,331.
Option D: 5,452 is less than 6,331.

2. Which is the greater number in the pair?667 or 670

Correct Answer: Correct answer is: B) 670.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Very Easy

Concept notes: The question requires comparing two numerical values to determine which is greater.

Common Mistakes: A common mistake could be misreading the numbers or not carefully comparing the digits.

Explanations: To compare 667 and 670, we start by comparing the hundreds place. Both numbers have 6 in the hundreds place. Next, we compare the tens place. The tens place in 667 is 6, and in 670 it is 7. Since 7 is greater than 6, 670 is the greater number.

Option Analysis:

Option A: 667 is not the greater number.
Option B: 670 is the greater number.

3. One million is ..... than one thousand

Correct Answer: Correct answer is: (D) More.

Exam Relevance: SAT, GRE, GMAT, ACT

Difficulty: Easy

Concept notes: The question is about comparing numerical values. One million (1,000,000) is a larger number than one thousand (1,000).

Common Mistakes: A common mistake could be confusing the terms "richer" or "cheaper" with numerical comparison, which are not applicable in this context.

Explanations: One million (1,000,000) is a larger numerical value than one thousand (1,000). Therefore, one million is more than one thousand.

Option Analysis:

Option A: "Cheaper" is not a valid comparison for numerical values.
Option B: "Richer" is not a valid comparison for numerical values.
Option C: "Less" would imply one million is smaller than one thousand, which is incorrect.
Option D: "More" correctly indicates that one million is a larger numerical value than one thousand.

4. 'Kevin ate 3 cookies. Ericson ate 3 times as many cookies as Kevin.' is an additive comparison.

Correct Answer: Correct answer is: B) False.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: In quantitative comparison, an additive comparison involves comparing quantities by adding or subtracting. A multiplicative comparison involves comparing quantities by multiplying or dividing.

Common Mistakes: A common misunderstanding is confusing additive and multiplicative comparisons. In this case, the statement involves multiplying the number of cookies Kevin ate by 3, which is a multiplicative comparison, not an additive one.

Explanations: The statement "Kevin ate 3 cookies. Ericson ate 3 times as many cookies as Kevin" involves a multiplicative comparison. This is because Ericson's number of cookies is determined by multiplying Kevin's number of cookies by 3. An additive comparison would involve adding or subtracting a certain number of cookies, not multiplying.

Option Analysis:

Option A: This option is incorrect because the statement describes a multiplicative comparison, not an additive one.
Option B: This option is correct because the statement describes a multiplicative comparison, not an additive one.

5. Which correctly compares 3.12 and 2.75?

Correct Answer: Correct answer is: (B) 2.75 < 3.12.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question tests the ability to compare decimal numbers.

Common Mistakes: A common mistake is to overlook the decimal places and compare only the whole numbers.

Explanations: To compare 2.75 and 3.12, we start by comparing the whole number parts. The whole number part of 2.75 is 2, and the whole number part of 3.12 is 3. Since 2 is less than 3, it follows that 2.75 is less than 3.12. Therefore, the correct comparison is 2.75 < 3.12.

Option Analysis:

Option A: 2.75 = 3.12 is incorrect because the numbers are not equal.
Option B: 2.75 < 3.12 is correct because 2.75 is less than 3.12.
Option C: 3.12 < 2.75 is incorrect because 3.12 is greater than 2.75.
Option D: 3.21 < 2.75 is incorrect because 3.21 is greater than 2.75.

6. Compare: 2 pints ..... 20 fluid ounces

Correct Answer: Correct answer is: (B) >.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: To compare 2 pints and 20 fluid ounces, we need to convert both quantities to the same unit.

Common Mistakes: A common mistake is to assume that 2 pints is equal to 20 fluid ounces without converting the units.

Explanations: 1 pint is equal to 16 fluid ounces. Therefore, 2 pints is equal to 2 * 16 = 32 fluid ounces. Since 32 fluid ounces is greater than 20 fluid ounces, 2 pints is greater than 20 fluid ounces.

Option Analysis:

Option A: Incorrect because 2 pints is not less than 20 fluid ounces.
Option B: Correct because 2 pints is greater than 20 fluid ounces.
Option C: Incorrect because 2 pints is not equal to 20 fluid ounces.
Option D: Incorrect because one of the other options is correct.

7. Which number is less than 10?

Correct Answer: Correct answer is: (C) 7.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Very Easy

Concept notes: The question asks for a number that is less than 10. We need to identify which of the given options is smaller than 10.

Common Mistakes: A common mistake could be misreading the question and selecting a number greater than 10.

Explanations: The number 7 is less than 10. The other options (11, 14, and 12) are all greater than 10.

Option Analysis:

Option A: 11 is greater than 10.
Option B: 14 is greater than 10.
Option C: 7 is less than 10.
Option D: 12 is greater than 10.

8. Which number is greater?

Correct Answer: Correct answer is: (B) 19.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Very Easy

Concept notes: The concept tested here is basic numerical comparison.

Common Mistakes: A common mistake could be misreading the numbers or confusing their order.

Explanations: The number 19 is greater than the number 15. This is determined by comparing the digits in each place value. Since 19 has a higher digit in the tens place (1) and the ones place (9) compared to 15 (which has 1 in the tens place and 5 in the ones place), 19 is the greater number.

Option Analysis:

Option A: 15 is not the greater number.
Option B: 19 is the greater number.

9. Five cups hold 1.2 L and 3 mugs hold 900 ml. Which hold more liquid, one cup or one mug?

Correct Answer: Correct answer is: (A) Mug.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: To determine which holds more liquid, one cup or one mug, we need to compare the volume each can hold.

Common Mistakes: A common mistake is to assume that because there are more cups, they must hold less liquid than the mugs.

Explanations: First, we calculate the volume of one cup: - Five cups hold 1.2 L. - Therefore, one cup holds \( \frac{1.2 \text{ L}}{5} = 0.24 \text{ L} \). Next, we calculate the volume of one mug: - Three mugs hold 900 ml. - Therefore, one mug holds \( \frac{900 \text{ ml}}{3} = 300 \text{ ml} \). Since 1 L = 1000 ml, 0.24 L = 240 ml. Comparing the volumes: - One cup holds 240 ml. - One mug holds 300 ml. Thus, one mug holds more liquid than one cup.

Option Analysis:

Option A: Mug holds more liquid, which is correct.
Option B: Cup holds more liquid, which is incorrect.

10. Select the smaller number in the pair:950 or 850

Correct Answer: Correct answer is: B) 850.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Very Easy

Concept notes: The concept tested here is the comparison of numerical values to identify the smaller number.

Common Mistakes: A common mistake would be to confuse the larger number with the smaller number, especially if the numbers are close in value.

Explanations: To determine the smaller number between 950 and 850, we compare the digits from left to right. The hundreds place in 950 is 9, and in 850 is 8. Since 8 is less than 9, 850 is the smaller number.

Option Analysis:

Option A: 950 is not the smaller number.
Option B: 850 is the smaller number.
