Question on notation

[![enter image description here](https://i.stack.imgur.com/28FIf.png)](https://i.stack.imgur.com/28FIf.png)


Here, when they write $v/(\mathrm{mol\ s^{-1}\ (kg\ \text{protein})^{-1}})$ is $0.30$ for the first row first column, do they mean that the value is $0.30\ \mathrm{mol\ s^{-1}\ (kg\ \text{protein})^{-1}}$ or $0.30/(\mathrm{mol\ s^{-1}\ (kg\ \text{protein})^{-1}})$? 




The expression
$$v/(\mathrm{mol\ s^{-1}\ kg^{-1}})=30$$
means
$$v=30\ \mathrm{mol\ s^{-1}\ kg^{-1}}$$


This notation is used in the table, so that the entries are all just numbers without any unit symbols.


For an explanation, I copy the following section from my [meta answer](https://chemistry.meta.stackexchange.com/a/2978/7951), which is mainly a collection of rules and examples taken from various standards and guides (see the meta answer for references).

Also note that expressions for units shall contain nothing else than unit symbols and mathematical symbols. Any attachment to a unit symbol as a means of giving information about the special nature of the quantity or context of measurement under consideration is not permitted. Therefore the use of the unit “$\mathrm{mol\ s^{-1}\ kg^{-1}\ \text{protein}}$” as written in the question is not permissible. The correct unit is $\mathrm{mol\ s^{-1}\ kg^{-1}}$.
