To find out what percent 110 is of 500, we can set up a proportion. Let \( x \) represent the percentage we want to find.
We can write the equation as follows:
\[ \frac{110}{500} = \frac{x}{100} \]
Next, we can cross-multiply to solve for \( x \):
\[ 110 \cdot 100 = 500 \cdot x \]
This simplifies to:
\[ 11000 = 500x \]
Now, divide both sides by 500 to isolate \( x \):
\[ x = \frac{11000}{500} \]
Calculating \( \frac{11000}{500} \):
\[ x = 22 \]
Thus, 110 is 22% of 500.
The final answer is:
\[ \boxed{22%} \]
