Fractions in the Fast Lane - A Response

This isn't something I like to admit, but I do use math in my daily life, or at least somewhat daily. To put it into a fraction. I use fractions outside of school 3/7 days of the week at the least. These 3 days of the week are the days that I go to the gym. Each day I go I know exactly how many reps of each exercise I do, and for most of them, I do 25 reps set out over 5 sets. So, using fractions I know how many more reps I need to do in order to complete my workout. Say I do one rep, that means I am 1/25th finished with doing that exercise. When I do the first part of a rep like in a squat where you descend, that descent would count as 1/50th of my workout, and the ascent would make it 1/25th of my workout.
