Question

in the form of p/q 2.58 58 under bar​

Answer 1

p/q = (258-2)/(100-1) = 256/99

Answer 2

let 2.58 bar be x

x=2.585858....

multiply 100 by both the sides

100×x = 2.5858....×100

100x=258.5858...

subtract the above two equations formed

100x-x=258.5858...-2.5858....

99x=256

x=256/99
