Answer 2

Solution:

_____________________________________________________________


Given & To find :

0.28 (bar) = 0.2828...

_____________________________________________________________


let the value of x be 0.28 bar,.

then,

100x = 100(0.28 bar) = 28.2828...

100x = 28 +0.2828...

100x = 28 +x

99x = 28,.

x = $\frac{28}{99}$ (it is in rationalised form)
