We are given that:

\[
\frac{9}{100} \times x = 9
\]

To find \( x \), follow these steps:

1. Multiply both sides of the equation by the reciprocal of \( \frac{9}{100} \), which is \( \frac{100}{9} \):

\[
x = 9 \times \frac{100}{9}
\]

2. Simplify the expression:

\[
x = 100
\]

Thus, \( x = 100 \).
