Explanation:

To easily work with the data and have a particular workbook fill the screen in Excel after using the Tiled selection under Arrange All, you should maximize the workbook window. This is done by clicking on the maximize button at the top right corner of the workbook window. Maximizing allows you to focus on a single workbook and utilize the entire screen space for that particular workbook. If needed, to adjust the display or make objects within Excel easier to work with, you can use tools like the Zoom button to magnify the display. Also, by clicking and dragging, you can reorganize sheet tabs or right-click sheet tabs to access the Sheet Shortcut menu for more options.

Furthermore, when preparing data for printing, the Page Layout tab provides diverse options to adjust the display of your worksheet to fit your needs better. The Scale to Fit group within this tab allows you to scale your worksheet to print on a single page, either by modifying the width, the height, or by selecting a Scale percentage which adjusts the height and width proportionately. Remember to consider the font size for readability when adjusting the scale.
