By default, Microsoft Word only puts three fractions into fraction form automatically. These fractions include ½, ¼ and ¾. No words are put into fraction form by default. With a few keyboard shortcuts, however, you can create word or number fractions. Instead of a slanted line, fractions are displayed with a clear numerator and denominator with a horizontal line between the two. Unlike using the Equation Editor, no additional installation is required to use this fraction method in Microsoft Word.

Place your cursor where you want the fraction in your Microsoft Word document.

Press "Ctrl" + "F9." This displays a gray box with field braces { }.

Type the following within the two braces without quotes: "EQ \F(numerator,denominator)." Replace numerator and denominator with your desired words or numbers.
For instance, if you want a word fraction with sad and happy, you would type "EQ \F(sad,happy).

Place your cursor inside the brackets.

Press "Shift" + "F9" to turn the gray box into your desired fraction.
Tips & Warnings
 If you have the Equation Editor installed, go to "Insert," select "Object" and select "Microsoft Equation." Follow the prompts to create and insert your fraction.
 If you receive "ERROR!" instead of your expected fraction, delete the erroneous fraction and start again. Before pressing "Shift" + "F9," use your arrow keys to move outside the fraction box completely. Arrow back until your cursor is sitting within the brackets and then press "Shift" + "F9." This happens occasionally and is a Microsoft Office glitch.
 The Equation Editor is not installed using the "Typical Installation" method in Microsoft Word. This means you will first have to install the feature before using it.
