UPDATED ACTUAL Exam Questions and
CORRECT Answers
Integer - CORRECT ANSWER a whole number that includes all positive numbers, negative
numbers, and 0; does not include decimals or fractions
Natural number - CORRECT ANSWER all positive or nonnegative integers, including 0;
does not include negative numbers, decimals, or fractions
Rational number - CORRECT ANSWER a number that can be expressed as a ratio or quotient
of two nonzero integers
How can rational numbers be expressed? - CORRECT ANSWER As common fractions or
decimals
Irrational numbers - CORRECT ANSWER A number that cannot be expressed as an exact
ratio of two integers
What is a characteristic of an irrational number in decimal form? - CORRECT ANSWER The
decimal will never terminate and never repeat
Define divisor and dividend - CORRECT ANSWER Divsor = number doing the dividing
Dividend = number being divided
Homogeneous fraction - CORRECT ANSWER fractions with the same denominator
common denominator - CORRECT ANSWER number that is a multiple of the original
denominators
, How do you multiply fractions? - CORRECT ANSWER Multiply the numerators and
denominators horizontally and then simplify the remaining product
Reciprocal fraction - CORRECT ANSWER a fraction with the numerator and denominator
switched
How do you divide fractions? - CORRECT ANSWER take the reciprocal of the second
fraction (the one doing the dividing) and multiply them together
What does a negative exponent indicate? - CORRECT ANSWER A reciprocal fraction
Expanded form - CORRECT ANSWER shows the place value of each digit; example 542 =
500 + 40 + 2, which is equal to 5 hundreds, 4 tens, and 2 ones
Prime numbers - CORRECT ANSWER natural numbers greater than 1 that are divisible only
by 1 and themselves (2, 3, 5, 7, 11, 13, 17, 19...)
Composite numbers - CORRECT ANSWER natural numbers greater than zero that are
divisible by at least one other number besides 1 and themselves; they have at least 3 factors, such
as 9 having 1, 3, and 9
prime factorization - CORRECT ANSWER writing the product of prime numbers that make
up the number
How do you perform prime factorization? - CORRECT ANSWER Factor a known prime
number into the given number; repeat on all factors until no more factorization can take place
Greatest common divisor - CORRECT ANSWER the largest positive integer that divides into
the numbers without producing a remainder
