terminating decimals- a decimal that ends or terminates.
example: 0.5, 0.84, 1.03.

repeating decimals- a decimal that ends with a repeated digit or block of digits.
_ _ _
example: 0.333, 0.1212, 0.777
you only put the line (-) to show that its a repeating decimal.


writing a repeating decimal as a fraction!
1. identify how many digits repeat.
2.place the repeating digits over the same number of 9's.
3. simplify.


when you do on a calculator 6 divided by 9 ( that is because where do the fraction 6\9) on the calculator screen only 10 digits come up. so when you do that it should come up as 0.6666666667. so as you can see there is a 7 at the end, if it could hold more than 10 digits then the number 6 would go on for ETERNITY'S so 7 comes up because the calculator automatically knows to round it up.
