LET X=O.2888.....(1)
SHIFTS THE decimal point just before the recurring term by multiplying the suitable power of 10
10X=2.8 88...(1)
MULTIPLY EQUATION by that power of 10 which is equal to the numbers of recurring digit.
100x=28.888...(2)
SUBSTRATE 1 and 2
100x-10x=28.888.....-2.888..
==>90x=26.
===>x=26/90
==>x=13/45
