To answer this question, we know that the percentage can be expressed as follows:
![n\%=(n)/(100)](https://img.qammunity.org/2023/formulas/mathematics/college/rz2r9atai9k9perrlksjnoaohudrntlquu.png)
Now, if we know that the n percent of 221 is 79.4, we can write the following equation:
![221\cdot(n)/(100)=79.4](https://img.qammunity.org/2023/formulas/mathematics/college/uw3511d8vy2ldvgztp9w88pyn6lqta5y18.png)
To solve this, we can multiply both sides by (100/221). Then we have:
![\begin{gathered} (100)/(221)\cdot(221)/(100)\cdot n=(100)/(221)\cdot79.4\Rightarrow(a)/(a)=1,(100)/(100)=1,(221)/(221)=1 \\ (100)/(100)\cdot(221)/(221)\cdot n=n \\ n=(100\cdot79.4)/(221) \\ n=35.92760181 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/pu36chvd4ezofa6h9be1puxlioyr58wut6.png)
Now, we can see that 79.4 is 35.92..percent of 221.
If we round the percentage to the tenth place, we have 35.9.
In summary, we can say that 79.4 is 35.9% of 221.
