To answer this question, we know that the percentage can be expressed as follows:
[tex]n\%=\frac{n}{100}[/tex]Now, if we know that the n percent of 221 is 79.4, we can write the following equation:
[tex]221\cdot\frac{n}{100}=79.4[/tex]To solve this, we can multiply both sides by (100/221). Then we have:
[tex]\begin{gathered} \frac{100}{221}\cdot\frac{221}{100}\cdot n=\frac{100}{221}\cdot79.4\Rightarrow\frac{a}{a}=1,\frac{100}{100}=1,\frac{221}{221}=1 \\ \frac{100}{100}\cdot\frac{221}{221}\cdot n=n \\ n=\frac{100\cdot79.4}{221} \\ n=35.92760181 \end{gathered}[/tex]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.
