Draw a vertical line. 2. 32 ÷ 8 = 4 3. How many minutes from 7:35 to 8:05? 30 4. This is the net of a 5. 3/4 of 12 = 6. 17 + 22 = 7. 9 x 9 = 8. Colour 0.8 of this shape. 9. 1/2 kg = g

The line should be drawn in the box provided, similar to the one already partially drawn by the student.

2. $32 \div 8 = ?$

The answer is $\boxed{4}$.

3. How many minutes from 7:35 to 8:05?

There are $\boxed{30 \text{ minutes}}$.

4. This is the net of a _____

The net consists of a square base and four triangular faces.
This is the net of a $\boxed{\text{square-based pyramid}}$.

5. $\frac{3}{4}$ of $12 = ?$

The answer is $\boxed{9}$.

6. $17 + 22 = ?$

The sum is $\boxed{39}$.

7. $9 \times 9 = ?$

The product is $\boxed{81}$.

8. Colour 0.8 of this shape.

$0.8 = \frac{8}{10}$.

To colour 0.8 of the shape, you need to colour 8 out of the 10 segments.

9. $\frac{1}{2}$ kg = _____ g

So, $\frac{1}{2}$ kg = $\boxed{500 \text{ g}}$.
