Answer:

1.23 (bar over 3)

let x = 1.23333 — 1

on multiplying 100 to 1

100x = 1.2333 * 100

100x = 123.333. — 2

on multiplying 10 to 1

10x = 1.2333 * 10

10x = 12.33333. — 3

on subtracting 3 from 2

100x - 10x = 123.3333 - 12.33333

90x = 111

x = 111/90

therefore, 1.23333 can be represented as 111/90 (a rational no.)
