{tex}\frac{ \sqrt{2} - 1}{ \sqrt{2} + 1} = a + b \sqrt{2} \\ \frac{ \sqrt{2} - 1 }{ \sqrt{2} + 1} \times \frac{ \sqrt{2 } - 1}{ \sqrt{2 } - 1} = a + b \sqrt{2} \\ \frac{ {( \sqrt{2} - 1) }^{2} }{2 - 1} = a + b \sqrt{2} \\ 2 + 1 - 2 \sqrt{2} = a + b \sqrt{2} \\ 3 - 2 \sqrt{2} = a + b \sqrt{2} \\ a = 3 \: and \: b = - 2{/tex}

Given =18.4848.....
Let x =18.4848....
As the repeating block contains 2 digits , we will multiply x with 100.
x *100=18.4848...*100
100x=1848.4848...
100x-x=1848.48...-18.48...
99x= 1830 .0
X =1830/99=610/33.

18.484848......
P/Q=18.4848...
Multiply on both sides by 100
P/Q*100=18.4848...*100
100P/Q=1848.4848...
100P/Q=1830+P/Q
100P/Q-1P/Q=1830
99PQ=1830
P/Q=1830/99
