To find what percent 108 meals is of 1080 meals using the percent proportion, you can set up the proportion as follows:
\[ \frac{108}{1080} = \frac{x}{100} \]
Where \(x\) is the percentage we want to find.
Now, we can solve for \(x\) by cross-multiplying:
\[ 108 \times 100 = 1080 \times x \]
This simplifies to:
\[ 10800 = 1080x \]
Next, divide both sides by 1080 to isolate \(x\):
\[ x = \frac{10800}{1080} \]
Now, perform the division:
\[ x = 10 \]
So, 108 meals is 10% of 1080 meals.
