Questions and Answers
  • 1. 

    27 is a prime number.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A prime number is a number that is only divisible by 1 and itself. However, 27 is divisible by 1, 3, 9, and 27, so it is not a prime number. Therefore, the correct answer is False.

    Rate this question:

  • 2. 

    A composite number has more than two factors.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A composite number is a positive integer that has more than two distinct positive divisors. This means that a composite number can be divided evenly by more than just 1 and itself. For example, the number 6 is a composite number because it can be divided evenly by 1, 2, 3, and 6. Therefore, the statement "A composite number has more than two factors" is true.

    Rate this question:

  • 3. 

    All prime numbers are odd.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because not all prime numbers are odd. The only even prime number is 2. All other prime numbers are odd.

    Rate this question:

  • 4. 

    The number 9 has one prime factor.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A prime factor is a prime number that divides another number evenly without leaving a remainder. The number 9 can be expressed as 3 x 3, where both factors are prime numbers. Therefore, the statement that the number 9 has one prime factor is true.

    Rate this question:

  • 5. 

    To find the product of number, We must divide.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This statement is incorrect. To find the product of numbers, we must multiply them, not divide. Division is used to find the quotient or the result of dividing one number by another.

    Rate this question:

  • 6. 

    To square a number, I must multiply the number by itself.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because squaring a number means multiplying the number by itself. For example, if we square the number 2, we get 2 x 2 = 4. So, in order to square any number, we need to multiply it by itself.

    Rate this question:

  • 7. 

    Average is sum divided by number.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the average of a set of numbers is calculated by summing all the numbers together and then dividing that sum by the total number of values in the set. This is a fundamental concept in mathematics and statistics.

    Rate this question:

  • 8. 

    The area of a square whose perimeter is 36 cm is 81 square cm.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The perimeter of a square is the sum of all its sides. In this case, the perimeter is 36 cm. Since a square has four equal sides, each side of the square would be 36 cm divided by 4, which is 9 cm. The area of a square is calculated by multiplying the length of one side by itself. Therefore, the area of this square would be 9 cm multiplied by 9 cm, which equals 81 square cm. Hence, the statement is true.

    Rate this question:

  • 9. 

    A  hexagon has 5 angles. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A hexagon has 6 angles, not 5. Each angle in a regular hexagon measures 120 degrees, so the total sum of all angles in a hexagon is 720 degrees. Therefore, the statement that a hexagon has 5 angles is false.

    Rate this question:

  • 10. 

    All quadrilateral have four equal sides.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement "All quadrilaterals have four equal sides" is false. Quadrilaterals can have sides of different lengths. Some examples of quadrilaterals with unequal sides include rectangles, squares, parallelograms, and trapezoids.
