$(8 \div 88) \times 8888088 = ?$

$\frac{0.009}{?} = 0.01$

What is the smallest value that must be added to $708$ so that the resultant is a perfect square?

The value of $3+\frac{3}{3+\frac{1}{3+\frac{1}{3}}}$ is:

If $a^{2}+b^{2}+\frac{1}{a^{2}}+\frac{1}{b^{2}}=4,$ then the value of $a^{2}+b^{2}$ will be

$\left\{7 \frac{1}{2} + \frac{1}{2} \div \frac{1}{2} \text{ of } \frac{1}{4} - \frac{2}{5} \times 2 \frac{1}{3} \div 1 \frac{7}{8} \text{ of } \left(1 \frac{2}{5} - 1 \frac{1}{3}\right)\right\} = ?$
