How can you compare 2 fractions by using a number line?

You can see how far apart they are and compare their legnth

The fraction which lies farther to the right on the number line is the larger of the fractions.

To compare two fractions using a number line, you can follow these steps:

Step 1: Draw a number line.
- Start by drawing a horizontal line on a piece of paper or a whiteboard. Label the line with numbers, ensuring that the distance between each number is equal. For example, you can label the line from 0 to 1, or from 0 to 10.

Step 2: Mark the fractions on the number line.
- Identify the two fractions that you want to compare, and plot them on the number line.
- For example, if you're comparing the fractions 2/5 and 3/4, you would mark 2/5 on the number line by dividing it into five equal parts and locating the second part. Similarly, for 3/4, divide the line into four equal parts and locate the third part.

Step 3: Compare the positions on the number line.
- Look at the position of the two fractions on the number line. The fraction that is located to the right, further along the line, corresponds to the larger value.
- In our example, if 2/5 is to the left of 3/4 on the number line, it means that 3/4 is greater than 2/5.

By using a number line, you visually represent the fractions and their positions relative to each other, making it easier to compare and determine which one is larger or smaller.
