What is

2/6 = 1/3   = .3333 repeating

5/6  = .8333     the 3's repeat

4/9 = .4444  repeating

2/3 =  .6666 repeating

[Each of these can be determined by taking the numerator and dividing by the denominator in a "long divsion" process ]

A repeating or recurring decimal is a way of representing rational numbers in base 10 arithmetic. The decimal representation of a number is said to be repeating if it becomes periodic (repeating its values at regular intervals) and the infinitely-repeated portion is not zero.
