### Can an irrational number be a decimal?

If you write an irrational number as a decimal, you would have
an infinite number of decimal places, and the digits wouldn't
repeat. That is, if you divide 1 by 7 for example, you get the
pattern 0.142857 142857 142857... repeating over and over; this
won't happen with an irrational number.
All irrational numbers are decimals which can not be expressed as
fractions

###### Asked in Numbers

### Are irrational numbers always decimal numbers?

Both rational and irrational numbers can be expressed with
decimals. If the number is irrational, it will have an infinite
number of decimal digits, and there will be no periodic repetition.
For example, 1/7 (which is rational) is 0.142857 142857 142857...
The same sequence of six digits repeats over and over again. In
irrational numbers, this is not the case.
