## Step 5: Types of Decimals

2/3=0.66666...

This is called a **repeating decimal** it goes on forever repeating the same digits over and over.

ex: 0.66666...., 0.123123123..., 0.104710471047...

to simplify this number you have two options.

1)put a line over the repeating digits

2)round the decimal off

Another type of decimal is a **terminating decimal**.

A terminating decimal is a decimal that stops.

ex: 1/8 = 0.125, 1/50 =0.02, 1/32 = 0.03125

The third type of decimal is a **irrational decimal**.

An irrational decimal is one that does not terminate or repeat.

ex: pi, the square root of 2, any other non-perfect square roots

To simplify this number you can:

1) Round it off to whatever place you choose.
