0 as an equivalent decimal. 3 0^1 ^0 .0^0 ^0 ^0

No matter how many zeros you write in the dividend,
the division just keeps on going. When the same
digit(s) repeat in the quotient, you have a
repeating decimal.

Alberto’s batting average is 0.3333... , or 0.333
when rounded to the nearest thousandth.

Every fraction can be renamed as a
terminating decimal or a repeating decimal.

A terminating decimal has a
definite number of decimal places.
When you divide, the remainder
is 0.

A repeating decimal has one
or more digits that repeat
indefinitely. When you divide,
the remainder is never zero.

Repeating decimals may be written with a barover
the digit or digits that repeat.

0.2727... 0.2 7  bar 5.13636.. .5.13 6  bar

Think
The digits 2 and 7
repeat indefinitely.

Think
The digits 3 and 6
repeat indefinitely. The
digit 1 does not repeat.
