Question 1
Which of the following represents a rational number?
A. π
B. √2
C. 2 ¾
D. √-1
Correct Answer: C. 2 ¾
Rationale: A rational number is any number that can be expressed as
a ratio of two integers (a fraction). 2 ¾ can be written as 11/4, a ratio
of two integers. π and √2 are irrational numbers, and √-1 is an
imaginary number.
Question 2
What is the result called when two values are multiplied together?
,A. Sum
B. Quotient
C. Product
D. Difference
Correct Answer: C. Product
Rationale: In mathematics, the result of multiplying two or more
values is called the product. The sum is the result of addition, the
quotient is the result of division, and the difference is the result of
subtraction.
Question 3
Which of the following is NOT a whole number?
A. 0
B. -1
C. 5
D. 20
Correct Answer: B. -1

Which property allows us to rearrange parentheses in addition and
multiplication without changing the result?
A. Commutative property
B. Associative property
, C. Distributive property
D. Identity property
Correct Answer: B. Associative property
Rationale: The associative property states that the grouping of
numbers in addition or multiplication does not affect the result. For
example, (a + b) + c = a + (b + c).
Question 6
What is the term for a number that can be written as the square of an
integer?
A. Rational number
B. Perfect square
C. Integer
D. Composite number
Correct Answer: B. Perfect square
