Answer:

see explanation

Explanation:

The dot above the 5 indicates the 5 is repeating , that is

2.7555...

We require 2 equations with the repeating 5 placed after the decimal point.

let x = 2.7555,,, ( multiply both sides by 10 and 100 )

10x = 27.55... → (1)

100x = 275.55... → (2)

Subtract (1) from (2), thus eliminating the repeating 5

90x = 248 ( divide both sides by 90 )

x =
(248)/(90) =
(124)/(45)
