__________________________________________
Note: Let's assume that this given decimal value is really:
"0.66666666666666666....." ;
(non-terminating; but repeating the singing digit, "7" ; yet rounded to:
" 0.66666667 " ;
then: " 0.666... " = ;
= (666 ÷ 111) / (999 ÷ 111) ;
= 6/9 ;
= (6÷3)/(9÷3) ;
= 2/3 ;
= " "
→ which is our answer.
____________________________________________
Or: " 0.6666... " = 666 ÷ 999 = ? ;
using calculator :
= 0.66666667 ;
→ which is the "rounded off" number of "0.6666..." ;
— (infinitely repeating) ;
→ So 666 ÷ 999 =
→ " " ;
= " " ;
→ Either use a "fraction calculator" ;
or simplify as aforementioned.
