Irrational Numbers
Rational Numbers
Integers
Whole Numbers
These are numbers that cannot be written as a ratio
Their decimal equivalents neither terminate nor repeat.
For example:
terminate or repeat
After the decimal, there are a finite number of digits. They terminate, or END. Ex.
After the decimal, there are one or more digits that repeat indefinitely. Ex.

2. divide Remember the TITANIC! Convert a FRACTION to a DECIMAL
All you have to do is ________________.
Remember
the TITANIC!
For example:
Convert the following fractions into decimals.
divide

3. You could turn the mixed number into a
Convert a MIXED NUMBER to a DECIMAL
You could turn the mixed number into a
fraction and divide (see above flip)
There are two ways to do this!
You could write the whole number portion as the whole number, and then just divide the decimal part.
