Microsoft Word can help you write everything from books to academic papers. Included in Microsoft Word 2007 and 2010 is a powerful equation editor that can insert formulas and mathematical symbols into Word documents. Whether you want to show a stacked fraction -- a traditional division symbol with one number above the other -- or a linear fraction with a common slash "/" symbol, the equation editor can handle it all.
Click the "Insert" tab.
Click the arrow next to "Equation" and then click "Insert new equation."
Click the type of division sign you want to insert into the document. For example, click "Fraction" and then click "Stacked Fraction" or "Linear Fraction," depending upon how you want your division symbol to look.
