45 is a number, not a unit.
It is 45/1.
It is 45/7 each.
If you don't give a unit how will people know what you are talking about. For example if I say my car is 45 what does that mean??? 45 years old, 45 horse power 45 feet long, 45 metres long, 45 tons get the idea ?
45 inches is an old unit of length called an "ell"
Subtracting 45 percent from 251.00 gives 251 x (1 - (45/100)) = 138.05. If the number refers to a unit of currency, don't forget to include the appropriate currency unit.
