Write the percent as a fraction or mixed number in simplest form. \[ 11 \frac{1}{8} \% \] \[ 11 \frac{1}{8} \%=\square \]

Step 1 ：Convert the mixed number to an improper fraction: \(11 \frac{1}{8} = \frac{11*8+1}{8} = \frac{89}{8}\)

Step 2 ：Divide the fraction by 100: \(\frac{89}{8} \% = \frac{89}{8*100} = \frac{89}{800}\)

Step 3 ：Simplify the fraction: The fraction \(\frac{89}{800}\) is already in its simplest form, as 89 and 800 have no common factors other than 1.

Step 4 ：\(\boxed{11 \frac{1}{8} \% = \frac{89}{800}}\)
