Answer:


(5)/(6)

Explanation:

We require 2 equations with the recurring value , 3 , placed after the decimal point.

let x = 0.8333... ( multiply both sides by 10 and 100 )

10x = 8.3333.. → (1)

100x = 83.333... → (2)

subtract (1) from (2) , thus eliminating the recurring value

90x = 75 ( divide both sides by 90 )

x =
(75)/(90) =
(5)/(6)

the rational fraction is
(5)/(6)
