Can rate of law be a decimal??

yes

No, the rate of law cannot be a decimal. The term "rate of law" does not have a specific meaning in common usage, so it is difficult to say for sure what you are referring to. However, rates are typically expressed as fractions or percentages, not decimals.

If you are referring to the "rate of change" in the context of mathematics or science, it is more commonly expressed as a decimal or a fraction. In this case, the rate of change represents the ratio of the change in a dependent variable to the change in an independent variable. It can take on any real value, including decimals.

If you are referring to a specific concept or law, please provide more context so I can provide a more accurate explanation.
