To find the number for which ninety percent equals 45, you can set up the equation:
\[
0.9 \times x = 45
\]
where \( x \) is the unknown number. To solve for \( x \), divide both sides of the equation by 0.9:
\[
x = \frac{45}{0.9}
\]
Calculating that gives:
\[
x = 50
\]
Therefore, ninety percent of 50 is 45. Thus, the number is **50**.
