Answer 1

Given:

Problems with half filled boxes.

To know:

Fill in the empty box.

Explanation:

$a\div b=\frac{a}{b}$

Solution:

We will solve as:

$\begin{gathered} A.\text{ }4\div\frac{16}{9}=\frac{9}{4} \\ B.\text{ }\frac{1}{9}=1\div9 \\ C.\text{ 7}\div9=\frac{7}{9} \\ D.\text{ 9}\div\frac{1}{9}=81 \end{gathered}$

Hence, sixteen by nine, one, nine and nine are the required values.
