4.

$√(64)=8\\\\8\frac17=8.14285714...\\\\8.\overline{14}=8.14141414...\\\\ \frac{15}2=7,5\\\\\\ \boxed{\ \frac{15}2\ \ \textless \ \ √(64)\ \ \textless \ \ 8.\overline{14}\ \ \textless \ \ 8\frac17\ }$

5.

√(18)

doesn't belong with the other three because it is irrational number
The other three can be expressed as a ratio between two integers.

$-\frac{10}2=\frac{-10\ }2\\\\-13.4=-13\frac4{10}=(-134)/(\ 10)\\\\ 22.\overline7=22\frac79=\frac{205}9\\\\\\ √(18)=√(9\cdot2)=\sqrt9\cdot\sqrt2=3\sqrt2$
