Which quotient is greatest?
- A.
8.31 ÷ 10
- B.
83.1 ÷ 100
- C.
83.1 ÷ 10
- D.
831 ÷ 1000
Correct Answer
C. 83.1 ÷ 10Explanation
The quotient 83.1 ÷ 10 is the greatest because when dividing 83.1 by 10, the result is 8.31. The other quotients are smaller: 8.31 ÷ 10 equals 0.831, 83.1 ÷ 100 equals 0.831, and 831 ÷ 1000 equals 0.831. Therefore, 83.1 ÷ 10 is the greatest quotient among the options given.Rate this question:

Use the order of operations to solve. 36 ÷ 3 −1 × 7
- A.
5
- B.
9
- C.
77
- D.
126
Correct Answer
A. 5Explanation
To solve this expression, we need to follow the order of operations, which states that we should perform multiplication and division before addition and subtraction. First, we divide 36 by 3, which equals 12. Then, we subtract 1 from 12, resulting in 11. Finally, we multiply 11 by 7, giving us the final answer of 77. Therefore, the given answer of 5 is incorrect.Rate this question:

What is the fifth term in the number pattern? 1; 20; 400; 8000;...
- A.
8,400
- B.
16,000
- C.
80,000
- D.
160,000
Correct Answer
B. 16,000Explanation
The pattern in the given number sequence is that each term is obtained by multiplying the previous term by 20. Starting with 1, we get 1 x 20 = 20, then 20 x 20 = 400, and so on. To find the fifth term, we multiply the fourth term (8000) by 20, which gives us 160,000. Therefore, the fifth term in the number pattern is 160,000.Rate this question:

What is the prime factorization for 48?
- A.
12 ∙ 4
- B.
6 ∙ 2^4
- C.
3 ∙ 2 ∙ 2^2
- D.
3 ∙ 2^4
Correct Answer
D. 3 ∙ 2^4Explanation
The prime factorization of 48 can be found by breaking down the number into its prime factors. Starting with the smallest prime number, which is 2, we divide 48 by 2 to get 24. We continue dividing by 2 until we can no longer divide evenly, which gives us 24 ÷ 2 = 12. Next, we divide 12 by the next smallest prime number, which is 3, to get 12 ÷ 3 = 4. Finally, we divide 4 by 2 to get 4 ÷ 2 = 2. Therefore, the prime factorization of 48 is 2^4 × 3, which can be written as 3 ∙ 2^4.Rate this question:

What is the GCF of 56 and 84?
- A.
4
- B.
12
- C.

- D.
28
Correct Answer
D. 28Explanation
The GCF (Greatest Common Factor) is the largest number that can evenly divide both 56 and 84. To find the GCF, we can list the factors of each number and find the largest common factor. The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The largest common factor between the two numbers is 28, so it is the GCF.Rate this question:

The length of a segment is 3/8 inch. How do you write the length as a fraction with a 16 as its denominator?
- A.
16/24
- B.
6/16
- C.
3/8
- D.
3/16
Correct Answer
B. 6/16Explanation
To write the length of a segment as a fraction with a denominator of 16, we need to find an equivalent fraction. Since 16 is a multiple of 8, we can multiply both the numerator and denominator of 3/8 by 2 to get the equivalent fraction. This gives us 6/16, which is the correct answer.Rate this question:

The largest pearl ever found was in the Philippines. Its diameter measures 5 1/2 inches. What is the diameter of the pearl as an improper fraction?
- A.
5 1/2 inches
- B.
7/2 inches
- C.
11/2 inches
- D.
19/2 inches
Correct Answer
C. 11/2 inchesExplanation
The given diameter of the pearl is 5 1/2 inches. To convert this mixed number into an improper fraction, we multiply the whole number (5) by the denominator (2) and then add the numerator (1). This gives us 11. The denominator remains the same (2). Therefore, the diameter of the pearl as an improper fraction is 11/2 inches.Rate this question:

Correct Answer
C. 168Explanation
The LCM (Least Common Multiple) of two numbers is the smallest multiple that is divisible by both numbers. To find the LCM of 24 and 28, we can list their multiples and find the smallest common multiple. The multiples of 24 are 24, 48, 72, 96, 120, 144, 168, ... and the multiples of 28 are 28, 56, 84, 112, 140, 168, .... The smallest common multiple is 168, which is divisible by both 24 and 28. Therefore, 168 is the LCM of 24 and 28.Rate this question:

Which of these fractions is NOT in order from least to greatest?
- A.
3/8, 3/9, 5/12
- B.
1/2, 7/12, 5/6
- C.
2/3, 3/4, 4/5
- D.
2/9, 3/10, 4/11
Correct Answer
A. 3/8, 3/9, 5/12Explanation
The fractions in the first option are 3/8, 3/9, and 5/12. To determine if they are in order from least to greatest, we can convert them to have the same denominator. The least common multiple of 8, 9, and 12 is 72. Converting the fractions, we get 27/72, 24/72, and 30/72. Comparing the numerators, we can see that 24/72 is the smallest, followed by 27/72, and then 30/72. Therefore, the fractions in the first option are not in order from least to greatest.Rate this question:

- D.
24/100
Correct Answer
B. 6/25Explanation
The decimal 0.24 can be written as the fraction 24/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4. Dividing 24 by 4 gives us 6, and dividing 100 by 4 gives us 25. Therefore, the simplest form of 0.24 as a fraction is 6/25.Rate this question:
