The advantage of a spreadsheet is that you can print your own look-up table and pin it to the wall. If you want fractions in your Excel spreadsheet, right click on the column, row or cell you want the fraction in, then select:
format cells > fractions > [select from list]
It will accept fractions as input, or generate fractions as output. There are standard options, or you can do pretty much anything with the custom option. For instance, if you want your input column in the form 1/87, 2/87 etc, do this:
select the column by right clicking at the top > format cells > custom > highlight the contents of the Type: box > type in ##/87 > OK
You don't have to type in all those fractions. Do the first two, highlight both cells , click on the square in the bottom right corner and drag it as far south as you want. The column will fill automatically.
If you go beyond 87/87 and the improper fractions offend you, then format the cells with # ##/87 and it will give them as proper fractions.
Incidentally, those who have been reading the 'Let's go metric but how?' thread and feel driven to invent their own tradition for formatting the date - for instance putting the year in the middle - can do it with the custom option.
