Representing 8/5 on a Number Line:

To represent the fraction 8/5 on a number line, we need to divide the number line into equal parts and locate the point that corresponds to the fraction. Here's how you can do it:

1. Divide the Number Line:
- Start by drawing a straight line horizontally.
- Choose a suitable scale for the number line. For example, you can mark every unit or divide each unit into smaller parts.
- Label the appropriate units on the number line. For instance, you can label the positive side of the number line as 1, 2, 3, and so on, and the negative side as -1, -2, -3, and so forth.

2. Locate the Fraction:
- To locate the fraction 8/5, start from zero (the origin) and move to the right side of the number line.
- Since 8/5 is greater than 1, we know it will fall somewhere between the numbers 1 and 2.
- Divide the space between 1 and 2 into five equal parts, as the denominator of the fraction is 5.
- Count eight equal parts from 1 in the direction of increasing numbers, and mark the point where you land. This point represents 8/5 on the number line.

Representing -8/5 on a Number Line:

To represent the fraction -8/5 on a number line, we follow a similar process as above, but this time we move in the opposite direction:

1. Divide the Number Line:
- Draw a straight line horizontally, just like before.
- Use the same scale and labeling method as mentioned earlier.

2. Locate the Fraction:
- Start from zero (the origin) and this time, move towards the left side of the number line because the fraction is negative.
- Since -8/5 is less than -1, it will fall between the numbers -1 and -2.
- Divide the space between -1 and -2 into five equal parts.
- Count eight equal parts from -1 in the direction of decreasing numbers and mark the point where you land. This point represents -8/5 on the number line.

Visual Representation:

Here's how the two fractions would look like on a number line:

```
-2 -1 0 1 2 3
──┬──┬───┬───┬───┬───
-8/5 8/5
```

In the above representation, the fraction -8/5 is to the left of -1, whereas the fraction 8/5 is to the right of 1 on the number line.

First: We divide 8/5 and than we got result of 1.6.

And we can easily represent 1.6 on a no. line like this:

<----_1---------0---------1-----1.6---2---------3---------->
