Number of children in six different classes are given below. Represented the data on a bar graph Class , Fifth 135, Sixth 120,eight 100, Nineth 90 tenth 80 a) how would you choose a scale?

To represent the given data on a bar graph, we need to choose an appropriate scale for the y-axis (the axis representing the number of children) so that the values can be clearly and accurately displayed. Here’s how you can choose a scale:

1. **Determine the range of data**: 
   - The highest value is 135 (for Class Fifth).
   - The lowest value is 80 (for Class Tenth).

2. **Choose a scale**: 
   - The scale should cover the range from 0 to at least 135.
   - It should be easy to plot and read the values. 

Considering the values, we can choose a scale where each unit represents 10 children. This will make the graph easy to read and plot. Here’s how the scale might look:

- 0
- 10
- 20
- 30
- 40
- 50
- 60
- 70
- 80
- 90
- 100
- 110
- 120
- 130
- 140

### Steps to Create the Bar Graph

1. **Draw the axes**: Draw a horizontal axis (x-axis) and a vertical axis (y-axis).

2. **Label the axes**:
   - The x-axis represents the different classes (Fifth, Sixth, Eighth, Ninth, Tenth).
   - The y-axis represents the number of children.

3. **Mark the scale on the y-axis**: Mark the scale from 0 to 140, with intervals of 10.

4. **Draw the bars**:
   - For Class Fifth, draw a bar up to 135.
   - For Class Sixth, draw a bar up to 120.
   - For Class Eighth, draw a bar up to 100.
   - For Class Ninth, draw a bar up to 90.
   - For Class Tenth, draw a bar up to 80.

5. **Label the bars**: Label each bar with the corresponding class name.

Here’s the data in tabular form to help visualize:

| Class  | Number of Children |
|--------|---------------------|
| Fifth  | 135                 |
| Sixth  | 120                 |
| Eighth | 100                 |
| Ninth  | 90                  |
| Tenth  | 80                  |
