100x = 247.4747.... (2)

(2) - (1)

99x = 245

x = 245/99

Answer 2

Answer:

let,

$2.47bar \\ \\ \\ now \\ x = 2.4747474747... eq(1)\\ \: \\ \\ multiplying \: by100 \\ 100x = 247.4747...eq(2) \\ subtracting \: eq(2)by(1) \\ \\ 100x - x = 247.4747.. - 2.474747.. \\ \\ 99x = 245 \\ x = \frac{245}{99}$
