1 Prime FactorizationPrime Number - Has exactly 2 factors, 1 and the number itselfComposite Number - Any whole number greater than 1 with more than 2 factors0 and 1 are neither prime nor compositePrime Factorization - Every composite number can be expressed as a product of prime numbers - FACTOR TREE
2 Divisibility Rules A number is divisible by: 2 if the ones digit is even3 if the sum of the digits is divisible by 35 if the ones digit is 0 or 56 if the number is divisible by 2 and 39 if the sum of the digits is divisible by 910 if the ones digit is 0
3 Equivalent Fractions-Two or more fractions that have the same quotient or that name the same region, part of a set, or part of a segment. ( 1/3 = 3/9)Fraction-A number that represents part of a whole, part of a set, or a quotient in theform a/b which can be read as a divided by bLike(common) Denominators-A whole number, greater than zero, that is the denominator of two or more fractions.(2/7 and 3/7 have like denominators)
4 Lowest terms(simplest form)-The form of a fraction in which the numerator and denominator have no common factor except 1Multiply(multiplication)-A mathematical operation of combining groups of equal amounts; repeated addition; the inverse of division.Unlike denominators-Two or more fractions with unequal denominators.(2/5 and 3/4 have unlike denominators)
6 Mixed Number-A number composed of an integer and a proper fraction Multiplicative inverse-The reciprocal of a number; in the set of real numbers the number a given number needs to be multiplied by to yield or equal 1.(7*1/7=1)Repeating decimal-A decimal in which one or more digits repeat infinitely.Terminating Decimal-A decimal whose digits do not repeat; all terminating decimals are rational numbers.
