To represent a rational number on a number line, you can follow these steps:

Draw a horizontal line. This will serve as your number line.

Determine the scale of your number line. Decide on a suitable unit of measurement and mark equal intervals along the line. For example, you could mark each unit as 1 cm, 1 inch, or any other consistent measurement.

Identify the rational number you want to represent. Let’s take the example of representing the rational number 3/4 on the number line.

Divide the number line between two consecutive whole numbers into equal intervals. For instance, if you have marked 0 and 1 as your whole numbers, divide the line segment between 0 and 1 into four equal parts.

Find the position of the rational number on the number line. In this case, 3/4 is located between 0 and 1. Since we divided this segment into four equal parts, count three of those parts starting from 0. The endpoint of the third part will represent the rational number 3/4.

Mark a point or draw a dot on the number line at the determined position. This point represents the rational number 3/4 on the number line.

Label the point with the corresponding rational number, in this case, 3/4.
By following these steps, you can represent any rational number on a number line. Remember to adjust the scale and division of intervals according to the specific rational number you are representing.
