What is the value of $9 \frac{1}{3} + 19 \frac{2}{3} + 20 \frac{3}{4} + 19 \frac{1}{4}$?

What approximate value will come in the place of the question mark $(?)$ in the following question? (You are not expected to calculate the exact value.)
$(32.13)^{2} + (23.96)^{2} - (17.11)^{2} = ?$

What will come in the place of the question mark $(?)$ in the following expression?
$\frac{28}{65} \times \frac{195}{308} \div \frac{39}{44} + \frac{5}{26} = ?$

The value of $\frac{(2.3)^{3}-0.027}{(2.3)^{2}+0.69+0.09}$ is

The value of $0.008 \times 0.01 \times 0.0072 \div (0.12 \times 0.0004)$ is

When $\left(\frac{1}{2}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6}\right)$ is divided by $\left(\frac{2}{5}-\frac{5}{9}+\frac{3}{5}-\frac{7}{18}\right),$ the result is:
