What you can do is convert a ratio of dimensioned numbers that have the same unit (or type of unit); the units cancel when you take the ratio. So for instance $0.14 is 2% of $7 [14c/700c = .02 = 2%], 3 cm is 30% of a decimeter, and if your time to run a kilometer reduces from 4 minutes to 3 minutes 36 seconds [240 seconds to 216 seconds] it has improved by 10%. Good Hunting! You could also say that $0.35875 is 35.875% of a dollar or that 0.75 lbs is 75% of a pound. Harley
