    Make it an improper fraction. The improper version of the mixed number 21 11/16 can be found by following these steps:

    21 11/16 = 21 × 16 + 11 / 16 = 347/16

    then divide this fraction by two

    347/2= 173.5

    16/2=8

    now you have a complex improper fraction, which you must convert back to a mixed number.

    The result is 7 and 11.5/18

    edit: convert the 18 to 16 since your tape measurer counts by sixteenths.

    Source(s): Hope this helps. It took me a second to think about. Btw, I used mental math, so you should check with a calculator. Or you could just multiply my final answer by two and see if it comes out to be 21 and 11/16.
