\(\begin{array}{l}
G = 2.4\sqrt 5 - 2.7\sqrt 5 + 2.6\sqrt 5 \\
= \left( {8 - 14 + 12} \right)\sqrt 5 \\
= 6\sqrt 5 \\
J = 5\sqrt 2 - \dfrac{{3\sqrt 2 }}{2} + 3.2\sqrt 6 \\
= \dfrac{{7\sqrt 2 }}{2} + 6\sqrt 6 \\
M = 2\sqrt 5 - 2\sqrt {10} + 3\sqrt 5 \\
= 5\sqrt 5 - 2\sqrt {10} \\
H = 2\sqrt 7 - 4.3\sqrt 7 + 7.4\sqrt 7 \\
= \left( {2 - 12 + 28} \right)\sqrt 7 \\
= 18\sqrt 7 \\
K = 3\sqrt 3 - 2.4\sqrt 3 + 5.2\sqrt 3 \\
= \left( {3 - 8 + 10} \right)\sqrt 3 \\
= 5\sqrt 3 \\
N = 2.2\sqrt 3 - 4\sqrt 3 + 3.3\sqrt 3 - 6\sqrt 3 \\
= \left( {4 - 4 + 9 - 6} \right)\sqrt 3 \\
= 3\sqrt 3 \\
I = 2\sqrt {11} - 4\sqrt {11} + 2.5\sqrt {11} \\
= \left( {2 - 4 + 10} \right)\sqrt {11} = 8\sqrt {11} \\
L = 5\sqrt 3 - 3.4\sqrt 3 + 2.5\sqrt 3 - \dfrac{1}{3}.6\sqrt 3 \\
= \left( {5 - 12 + 10 - 2} \right)\sqrt 3 \\
= \sqrt 3 \\
O = 7\sqrt 7 - 4\sqrt 7 - 3\sqrt 7 - \sqrt {21} \\
= \left( {7 - 4 - 3} \right)\sqrt 7 - \sqrt {21} \\
= - \sqrt {21}
\end{array}\)
