Answer:

[tex]\frac{126}{99}[/tex]

Step-by-step explanation:

assuming 1.2727... has 27 repeating then

create 2 equations with the repeated digits after the decimal point

let x = 1.2727.... → (1)

multiply both sides by 100

100x = 127.2727... → (2)

subtract (1) from (2) to eliminate the repeating part

99x = 126 ( divide both sides by 99 )

x = [tex]\frac{126}{99}[/tex]
