Pearson Math Course 2 Chapter 2

multiple

..... of a number is the product of that number and any nonzero whole number

terminating decimal

a decimal that stops, or terminates is a xxxx

power

a number that can be expressed using an exponent (Ex. The number 125 is a ........ of 5 because it can be written as 5 x 5 x 5)

rational number

a number that can be written as a quotient of two integers, where the divisor is not 0. 2/5, -6, 3 1/2,

base

a number that is used as a factor how many times the exponent of that number tells you

scientific notation

a shorter way to write numbers as the product of two factors - one factor is greater than or equal to 1 and less than 10 - the other factor is a power of 10.

composite number

a whole number greater than 1 that has more than two factors

factor

a whole number that divides another whole number with a remainder of 0

prime number

a whole number with exactly two factors, 1 and the number itself. the number 1 is neither prime or composite

equivalent fractions

fractions that name the same amount are xxxx (3/4, 6/8, 9/12)

improper fraction

has a numerator that is greater than or equal to its denominator (5/2,12/12, 8/3)

repeating decimal

if the same block of digits in a decimal repeats without end, the decimal is a xxx

least common denominator (LCD)

of two or more fractions is the least common multiple of their denominators

greatest common factor

of two or more numbers is the greatest number that is a factor of all the numbers

least common multiple (LCM)

of two or more numbers is the least multiple that is common to all the numbers (lcm of 3 and 4 is 12)

mixed number

sum of a whole number and a fraction

exponent

tells how many times a number, or base, is used as a factor

simplest form

when the numerator and the denominator of a fraction have no common factors other than 1 the fraction is written in ..........

prime factorization

writing a composite number as the product of its prime factors shows its ......
