Q1 QUESTION 1 OF 111
whole number
CORRECT ANSWER
set of numbers that contains no fractions or decimals
(0,1,2,3,4,189, 293)
RATIONALE
Whole numbers are non-negative integers, encompassing zero and all positive counting numbers
without any fractional or decimal components. This set represents discrete, indivisible quantities.
Q2 QUESTION 2 OF 111
Intergers
CORRECT ANSWER
whole numbers and their opposites (negatives)
(-1, -2, -3, -4, -5, 0, 1, 2, 3, 4, 5
RATIONALE
Integers encompass all whole numbers, including zero, and their negative counterparts, representing
quantities on a number line that extend infinitely in both positive and negative directions. This
definition distinguishes them from natural numbers (positive whole numbers) and rational numbers
(which include fractions and decimals).

, Q3 QUESTION 3 OF 111
prime number
CORRECT ANSWER
number that is only evenly divisible by 1 & itself
- no remainder or decimal
RATIONALE
A prime number is defined by its unique divisors; it is a natural number greater than 1 that has no
positive divisors other than 1 and itself. This property ensures that division by any other number will
result in a remainder or a non-integer quotient.
Q4 QUESTION 4 OF 111
composite number
Page 3
, CORRECT ANSWER
positive integer (whole number) formed by multiplying 2 smaller integers together
- all divisible by 2
- can be evenly divided by numbers other than 1 or itself
RATIONALE
A composite number is a positive integer with factors other than 1 and itself, meaning it can be
expressed as the product of two smaller positive integers. This definition inherently excludes prime
numbers and 1, and implies divisibility by numbers other than 1 or the number itself.
Q5 QUESTION 5 OF 111
decimals
CORRECT ANSWER
what follows decimal is a value less than 1 & added to the integer number preceding the decimal
- division between the whole portion & the fraction (or decimal) portion of a number
- EX: 3.15 3=whole; .15=decimal/fraction
RATIONALE
A decimal represents a fractional part of a whole number, where digits to the right of the decimal point
signify values less than one, added to the integer preceding it. This notation effectively divides the
whole and fractional components of a number, as seen in 3.15 where 3 is the whole and .15 is the
fractional part.
Q6 QUESTION 6 OF 111
real numbers
CORRECT ANSWER
rational and irrational numbers
RATIONALE
Real numbers encompass both rational numbers, which can be expressed as a fraction of two integers,
and irrational numbers, which cannot. This inclusivity defines the complete set of numbers on the
number line.
