When solving a "working together" application, if t represents the time that it takes to complete a specific job, then what does the expression startfraction 1 over t endfraction 1 t represent?

Hello there!

t is the time that it takes to complete a job:

this means that t = job

suppose t is in hours; then 1/t represents the proportion of the job that you can do in one hour.

Example:

you need 7 hours to do your job if you work at a constant rate; the amount of job done per hour is = 1/7, meaning that in one hour you complete a 1/7 of the total job.
