1. $\frac{\sqrt{2}\cdot \:2+1-\sqrt{5}\cdot \:2}{2}$

2. $-\pi -0.00908\dots$

Explicación paso a paso:

1. Procedimiento:

$\sqrt{2}+\frac{1}{2}-\sqrt{5}\\\\\sqrt{2}=\frac{\sqrt{2}\cdot \:2}{2},\:\sqrt{5}=\frac{\sqrt{5}\cdot \:2}{2}\\\\=\frac{\sqrt{2}\cdot \:2}{2}+\frac{1}{2}-\frac{\sqrt{5}\cdot \:2}{2}\\\\=\frac{\sqrt{2}\cdot \:2+1-\sqrt{5}\cdot \:2}{2}$

2.Procedimiento:

$\frac{5}{3}-\pi +0.97-\sqrt{7}\\\\\frac{5}{3}=1.66666\dots \\\\=1.66666\dots -\pi +0.97-\sqrt{7}\\\\\sqrt{7}=2.64575\dots \\\\=1.66666\dots -\pi +0.97-2.64575\dots \\\\=1.66666\dots -\pi +0.97-2.64575\dots \\\\=-\pi -0.00908\dots$
