See a solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as x/100.

Therefore we can write and equation to solve for x as:

x/100 = 39/40

color(red)(100) xx x/100 = color(red)(100) xx 39/40

cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = 3900/40

x = 97.5

39/40 = 97.5%
