Answer 2

[0010001111]... Hello User...[1001010101]
Here's your answer...

First, we will rationalise the fraction.
$\frac{ \sqrt{2} - 1 }{ \sqrt{2} + 1} \\ = \frac{ \sqrt{2} - 1 }{ \sqrt{2} + 1 } \times \frac{ \sqrt{2} - 1 }{ \sqrt{2} - 1 } \\ = \frac{ {( \sqrt{2} - 1) }^{2} }{ { \sqrt{2} }^{2} - {1}^{2} } \\ = \frac{2 - 2 \times \sqrt{2 } \times 1 + 1}{2 - 1} \\ = 3 - 2 \sqrt{2} \\ = 3 - 2 \times 1.414 \\ = 3 - 2.828 \\ = 0.172$
I think the value of root 2 is 1.414 and not 1.4114
