As given it is a terminating decimal, and as a fraction it is 6666/10000
However,as a recurring decimal to infinity, it can be converted to a ratio/fraction .
Hence
Let P = 0.66666....
10P = 6.66666....
Subtract
9P = 6.0 (Note the recurring decimal subtract to 'zero'.
Hence
9P = 6
P = 6/9
Cancel down by '3'
P = 2/3
NB Resurring decimals to infinity are written as 0.666... ( Note the three or more dots. This indicates to mathematicians, that it recurs to infinity, otherwise it is a terminating decimal.
NNB Irrational Numbers are those that recur to inifinity AND the decimal digits are not in any regular order. . 'pi' 3.141592.... being the most well known irrational number.
