Answer:
The given two rational numbers are 5/7 and 9/11.
5/7 = 0.7142857…..
9/11 = 0.81818……
take lcm of 7 and 9 that is 63
now multiply 63=7×9 , : 5×9=45
63=9×7
now write three numbers between 45 and 63
let it be 46/63, 49/63 and 52/63
The three irrational numbers are
0.73015873016
0.0.77777777778
0.8253968254
