prime numbers - ✔️✔️a number which can only be divided by itself and 1
prime number examples - ✔️✔️2, 3, 5, 7, 11, 13, 17, 19, 23, 29.....
prime factorization - ✔️✔️Breaking down a composite number until all of the factors are
prime
composite numbers - ✔️✔️A whole number greater than 1 that has more than two factors.
rational number - ✔️✔️A number that can be written as a fraction
irrational numbers - ✔️✔️Numbers that cannot be expressed as a ratio of two integers.
Their decimal expansions are nonending and nonrepeating.
covert decimal to percent - ✔️✔️move decimal two places to the left ex. 0.23=23%
Convert percent to decimal - ✔️✔️Move the decimal two places to the left ex. 700%=7.00
convert percentage to fraction - ✔️✔️1. change the percentage to a fraction

2. reduce the fraction
EX: 35% = 35/100 = 7/20
convert fraction to decimal - ✔️✔️Divide numerator by denominator
multiplying fractions - ✔️✔️multiply the numerators and multiply the denominators
reciprocal of a nonzero number fraction - ✔️✔️a/b x b/a=1 ex. 3/4 x 4/3= 1
divide a fraction by a fraction - ✔️✔️multiply the fraction by the other fractions reciprocal
a/b / c/d= a/b x d/c ex. 3//6= 3/4 x 6/5= 18/20
least common multiple - ✔️✔️The smallest multiple (other than zero) that two or more
numbers have in common.
least common denominator - ✔️✔️The least common multiple of the denominators of two
or more fractions.
Multiply Decimals - ✔️✔️Multiply like normal, the decimals do have have to align, add the
decimal places of both numbers together, the product's decimal places will be the sum
of decimal places from both numbers
Dividing Decimals by Decimals - ✔️✔️Move the decimal in the number outside the box
over as many places as you need to to make it a whole number. Then do the same with
the number inside the box. If the 2nd number still has a decimal, bring it up and divide
normally
