Mean Method to Find Rational Numbers between 9 and 7
To find four rational numbers between 9 and 7 using the mean method, we need to calculate the mean of the two numbers and generate rational numbers between them.

Step 1: Finding the Mean
- Add 9 and 7: 9 + 7 = 16
- Divide the sum by 2: 16 / 2 = 8

Step 2: Generating Rational Numbers
- The mean, 8, will act as the midpoint for our rational numbers.
- To find the first rational number, we take the mean of 9 and 8: (9 + 8) / 2 = 8.5
- To find the second rational number, we take the mean of 8 and 7: (8 + 7) / 2 = 7.5
- To find the third rational number, we take the mean of 8.5 and 8: (8.5 + 8) / 2 = 8.25
- To find the fourth rational number, we take the mean of 8 and 7.5: (8 + 7.5) / 2 = 7.75
Therefore, the four rational numbers between 9 and 7 using the mean method are 8.5, 7.5, 8.25, and 7.75. These numbers are evenly distributed between 9 and 7, with 8 acting as the midpoint. This method helps in finding rational numbers that are closer to the given range by using the average or mean value as a reference point.
