decimal number

A numeral that contains a decimal point to show the part of the number that is less than one. example 1.234

binary

A way of representing information using only two options, 1 and 0.

prime number

A whole number greater than 1 that has exactly two factors (1 and itself)

composite number

A whole number greater than 1 that has more than two factors. any whole number that is not a prime number. example, 8 has the factors of 1,2,4, and 8

integer

All whole numbers (both positive and negative) and zero. do not include fractions, decimals, or mixed numbers. ex. 0, 1, -1,

proper fraction

a fraction in which the numerator is less than the denominator

improper fraction

a fraction whose numerator is larger than the denominator

mixed number

a number made up of a whole number and a fraction

decimal point

a symbol used to separate the ones place from the tenths place in decimals or dollars from cents in currency.

true

any improper fraction can be written as mixed number

even number

any integer that can be divided by 2 without leaving a remainder. it can be shown as 2 equal parts. An even number has 0, 2, 4, 6, or 8 in the ones place.

odd number

any number that is not divisible by 2.

irrational numbers

cannot be written as fractions or decimals because the number of decimal places in infinite and there is no recurring pattern of digits within the number. example pi begins with 3.141592 and continues without terminating or repeating, so pi is an ________ number. Numbers that cannot be expressed as a ratio of two integers. Their decimal expansions are nonending and nonrepeating.

4/5 is 0.8 X 100 (8x10 over 10x10) is 80/100 is 80%

convert 4/5 to a decimal and to a percent

1 + 3/5 = 3/5 + 5/5

convert 8/5 to improper fraction

2+2/3

convert improper to mixed fraction: 8/3

24.36/100 or 2436/10,000 (reduced form is 609/2500) decimal form: 24.36/100= 0.2436

convert to fraction 24.36% to decimal

70/100 is equal to 70% ; 0.70 (decimal) ; 7/10 (simplified)

convert to percent 70/100; decimal, and simplified

23%

decimal to percent: 23

8.0003

eight and three-ten thousandths

rational numbers

incude all integers, decimals, and fractions. any terminating or repeating decimal number is a rational number.

fraction

is a number that is expressed as one integer written above another integer, with a dividing line between (x/y) -top number is the numerator (total number of parts under consideration) -bottom number is the denominator (total equal parts) *cannot have a denominator zero (undefined)

percent to decimal: 86%

decimal place

the position of a number to the right of the decimal point. In the decimal 0.123, the 1 is in the first place to the right of the decimal point, indicating tenths; the 2 is in the second place, indicating hundredths; and the 3 is in the third place, indicating thousandths.

real numbers

the set of all rational and irrational numbers

move the decimal point two places to the right

to convert from a decimal to a percent

move it two places to the left

to convert from a percent to a decimal

0.009
