Original Average Calculation

- The sum of the 20 numbers is 20 x 12 = 240.
- To find the average, we divide the sum by the total number of numbers: 240 / 20 = 12.
- Therefore, the original average of the 20 numbers is 12.


New Average Calculation after Dividing by 4

- When each number is divided by 4, the sum of the numbers will also be divided by 4.
- Therefore, the new sum of the numbers will be 240 / 4 = 60.
- Since there are still 20 numbers, the new average will be the new sum divided by the total number of numbers: 60 / 20 = 3.
- Therefore, the new average of the 20 numbers after dividing each number by 4 is 3.
