Respuesta :
If you make a mistake entering data in a cell you need to click in the cell and enter the correct information and then hit return. This action will delete the old information and replace it with the most recent information that you entered.
Answer:
You should click on the cell A15 and enter 123.
Explanation:
If you entered 567 in the cell A15 and you should have entered 123, to correct this mistake you can click on the cell A15 again and enter 123 which will eliminate the 567 that you had previously enter and 123 will appear in the cell.
