Why are all fractions in the formulae for finding the units of quantities ignored?

• Fractions are constants

• The Tellis Law states that the variety of the numbers that could be used in the formulae could have an effect on the resulting unit

• Having a number in the formula would cause too much confusion

• Only whole numbers are accepted
