    • A number that is always a prime number.

    • Two numbers that add to give you a sum.

    • One or two whole numbers that multiply to give you a product.

    • Two numbers that subtract to give you a difference.

    Correct Answer
    A. One or two whole numbers that multiply to give you a product.
    Explanation
    A factor is defined as one or two whole numbers that multiply together to give a product. It is not necessarily a prime number, nor is it related to addition or subtraction. Factors are used to divide a number evenly and are an important concept in mathematics.

    Rate this question:

  • 4.

    • 1,2,3,4,6,9,12,18

    Correct Answer
    A. 1,2,3,4,6,9,12,18,36
    Explanation
    The factors of a number are the numbers that can divide it evenly without leaving a remainder. In this case, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. These numbers can all divide 36 without leaving a remainder.

    Rate this question:

    What if the definition of a composite number?

    • A number with one and itself as a factor.

    • A number with 2 or more factors.

    • A number the shows the multiple of 2.

    • A number with 3 or more factors

    Correct Answer
    A. A number with 2 or more factors.
    Explanation
    A composite number is a number that has more than two factors. This means that it can be divided evenly by at least two different numbers, in addition to one and itself. For example, the number 12 is a composite number because it can be divided evenly by 1, 2, 3, 4, 6, and 12. In contrast, a prime number only has two factors, 1 and itself. Therefore, the correct answer is "A number with 2 or more factors."

    Rate this question:

  • 7. 

    Method 1: For creating multiples requires that you 

    • Add the multiple to three factors

    • Take the multiple and cut it in half

    • Add the multiple to another factor (i.e. multiple plus 1, multiple plus 2 etc. )

    • Multiply the multiple by another factor (i.e. multiple times 1, multiple times 2 etc. )

    Correct Answer
    A. Multiply the multiple by another factor (i.e. multiple times 1, multiple times 2 etc. )
    Explanation
    To create multiples of a number, you multiply the multiple by another factor (i.e., you perform multiplication using the original number and a different factor). For example, if you want to create multiples of 5, you can multiply 5 by 2, 3, 4, etc., to generate the multiples 10, 15, 20, and so on.

    Rate this question:

  • 8. 

    TRUE OR FALSE72 has 12 factors and 11 proper factors? 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The number 72 has 12 factors because it can be divided evenly by 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. It also has 11 proper factors because it excludes the number itself, so the proper factors are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36. Therefore, the statement is true.

    Rate this question:

  • 9. 

    The world multiple refers to:

    • A number that can be divided by another number with 2 factors.

    • A number that can be divided by another number without a remainder.

    • A number that can be divided by 2 and another number without a remainder.

    • A number that can be divided by another number leaving an even number as your answer.

    Correct Answer
    A. A number that can be divided by another number without a remainder.
    Explanation
    The correct answer is "a number that can be divided by another number without a remainder." This is because when we say a number is "multiple" of another number, it means that the first number is divisible by the second number without leaving any remainder. In other words, the first number can be expressed as the product of the second number and some integer.

    Rate this question:

  • 10. 

    The Factors of 32 are:*PLACE IN ORDER FROM LEAST TO GREATEST**Only put commas in between number do not leave spaces*

    Correct Answer

    1, 2, 4, 8, 16, 32
    1,2,4,8,16,32
    1,2,4,8,16,32
    Explanation
    The correct answer is 1, 2, 4, 8, 16, and 32. The factors of a number are the numbers that can divide evenly into that number without leaving a remainder. In this case, the factors of 32 are 1, 2, 4, 8, 16, and 32 because these numbers can all divide evenly into 32.

    Rate this question:

  • 11. 

    Method 2 for creating multiples requires that you 

    • Add the multiple to the previous answer or product.

    • Divide each product by a factor

    • Add half of each multiple to the answer or product.

    • Multiply each product by 3

    Correct Answer
    A. Add the multiple to the previous answer or product.
    Explanation
    In Method 2 for creating multiples, the correct approach is to add the multiple to the previous answer or product. This means that each time a multiple is generated, it should be added to the previous answer or product to obtain the next multiple. This method ensures that the multiples are incrementally generated by continuously adding the same value to the previous result.

    Rate this question:

  • 12. 

    When writing the proper factor or a number you DO NOT include:

    • The number 1

    • The number it self.

    • The number 0.

    • Any number that repeats.

    Correct Answer
    A. The number it self.
    Explanation
    When writing the proper factor or a number, you do not include the number itself because a proper factor is a factor of a number that is less than the number itself. For example, the proper factors of 6 are 1, 2, and 3, but 6 is not considered a proper factor because it is the number itself.

    Rate this question:

  • 13. 

    What are the proper factors of 24?

    • 4,6

    • 1,2,3,4,6,8,12,

    • 8,3

    • 1,2,3,4,6,8,12, 24

    Correct Answer
    A. 1,2,3,4,6,8,12,
    Explanation
    The proper factors of a number are all the factors of that number except for the number itself. In this case, the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. However, since we are looking for proper factors, we exclude 24 from the list. Therefore, the proper factors of 24 are 1, 2, 3, 4, 6, 8, and 12.

    Rate this question:

    Correct Answer
    64, 128, 192, 256, 320
    Explanation
    Multiples of a number are found by multiplying the number by integers (1, 2, 3, 4, and so on). The first five multiples of 64 are:
    64 × 1 = 64,
    64 × 2 = 128,
    64 × 3 = 192,
    64 × 4 = 256,
    64 × 5 = 320.
    Hence, the correct answer is 64, 128, 192, 256, and 320.
