Let the number of attendees who went to the job fain in 2018 be x.
Let the total number of attendees be y.
To find the percentage of attendees in 2018, we will divide the number of attendees in 2018 by the total number of attendees and then multiply the quotient by 100 to get the percentage.
Based on this, the formula would be as follows:
(x/y) * 100
