See a solution process below:

First, execute the Multiplication and Division operations left to right:

$9 (4) + 92 - \frac{10}{21} \Rightarrow$ $color(red)(9)(color(red)(4)) + 92 - color(blue)(10)/color(blue)(21) =>$

$36 + 92 - 0 . ¯ ¯¯¯¯¯¯¯¯¯¯ ¯ 476190$ $36 + 92 - 0.bar476190$

Now, execute the Addition and Subtraction operations from left to right:

$36 + 92 - 0 . ¯ ¯¯¯¯¯¯¯¯¯¯ ¯ 476190 \Rightarrow$ $color(red)(36) + color(red)(92) - 0.bar476190 =>$

$128 - 0 . ¯ ¯¯¯¯¯¯¯¯¯¯ ¯ 476190 \Rightarrow$ $128 - 0.bar476190 =>$

$127 . ¯ ¯¯¯¯¯¯¯¯¯¯ ¯ 523809$ $127.bar523809$
