To find out what number 39.16 is 22.25% of, you can set up the equation:
\[ \text{Let } x \text{ be the number.} \]
\[ 22.25\% \text{ of } x = 39.16 \]
To solve for \( x \), first convert 22.25% to a decimal by dividing by 100:
\[ \frac{22.25}{100} = 0.2225 \]
Then, set up the equation:
\[ 0.2225x = 39.16 \]
To solve for \( x \), divide both sides of the equation by 0.2225:
\[ x = \frac{39.16}{0.2225} \]
\[ x = 176 \]
So, 39.16 is 22.25% of 176.
