So unit rate is 23
Explanation:
Unit rate means: how many of one thing you have got for 1 of something else. So you end up with something like.

\frac{count of some thing}{1 of ssomething else} \Rightarrow unit rate

So for

\frac{$ 161}{7 s h a r e s}

. The unit rate is the cost of 1 share
Using the principle of ratios:
Change the 7 shares into 1 share by dividing by 7
For multiply and divide; what you do to the bottom you do to the top.

\frac{$ 161}{7 s h a r e s} \equiv \frac{161 \div 7}{7 \div 7} = \frac{23}{1}

Note that the sign

\equiv

means equivalent
