How do you type mixed number in Microsoft Word?

Type the integer portion in the same font and size as surrounding text, type a space, then type the numerator of the fraction, a slash </>, the denominator and another space. For common fractions like 1/2 and 3/4, Word (at least recent versions) will automatically replace the multi-character fraction with a single-glyph fraction character. If this doesn't happen--for example, if your fraction is 11/64--select the numerator, and Format>Font>Superscript, then the denominator, and Format>Font>Subscript. This will not, sadly, produce typography matching the automatically-inserted fraction glyphs, so if you have a lot of mixed numbers, you have to stop the automatic replacement process. On the Mac, you do it by selecting Word>Preferences>AutoCorrect>AutoFormat as You Type then unchecking Replace as you type: Fractions (1/2) with fraction character ½.
