How to Type Fractions in Microsoft Word & Mac Version
Most font types have symbols for common fractions, such as 1/2. This is true for Mac and Windows fonts. On a Windows system, Microsoft Word will automatically correct these common fractions as you type. Even though common fractions are available in many Mac fonts, Apple computers do not provide the fraction auto-correct functionality in the Mac version of Word. To type additional fractions on a Windows system, or to type any fractions on a Mac, you must insert the fraction as an equation in the document. The process is the same in both versions of Word.
Click the "Insert" tab in Word and click the "Equation" icon.
Click "Fraction" and select the layout of the fraction you want to create. Choose from a stacked, skewed, linear or small fraction.
Enter the numerator and the denominator of the fraction in the small text boxes that appear. Click outside the squares to save the fraction and type the rest of your document.
