I have been searching the UEB rule book for information on use of the colon in analogies. Did this change or are we still using (5, 2) is to and (56, 23) as?
See Section 3.17 of UEB. Use dots 25 for the ‘is to’ and dots 25, 25 for the ‘as’. We are still using ratio and proportion for these symbols…just the UEB version.
