27' 9 is a measurement of some unspecified nature: it could befeet and inches or minutes and seconds (of time or degrees). Whoknows? You know but you are not telling! Since there are 12 inchesin a foot, and 60 seconds in a minute, the conversion from theminor unit (for the 9 in the question) to the major unit (for 27')is unknown. It is, therefore impossible to answer the question.
