$II.$ $\sqrt{17}+\sqrt{11} > \sqrt{15}+\sqrt{13}$

$4 \frac{3}{4} + 2 \frac{1}{8} + 7 \frac{1}{4} + 3 \frac{7}{8} + 11 \frac{12}{13} = ?$

If the numbers $\frac{3}{5}, \frac{2}{3}, \frac{3}{4}$ are given,then we can say that

What is $x$ if $x^{2} - 1.5^{2} - 0.9^{2} = 2.43$?

The value of $\frac{3}{1^{2} \cdot 2^{2}}+\frac{5}{2^{2} \cdot 3^{2}}+\frac{7}{3^{2} \cdot 4^{2}}+\frac{9}{4^{2} \cdot 5^{2}}+\frac{11}{5^{2} \cdot 6^{2}}+\frac{13}{6^{2} \cdot 7^{2}}+\frac{15}{7^{2} \cdot 8^{2}}+\frac{17}{8^{2} \cdot 9^{2}}+\frac{19}{9^{2} \cdot 10^{2}}$ is
