8 times a number equals 128 . what is the number? equation

To find the number, let's denote it as \( x \). The problem states that 8 times a number equals 128. The equation for this is:

\[
8x = 128
\]

To solve for \( x \), divide both sides of the equation by 8:

\[
x = \frac{128}{8} = 16
\]

So, the number is \( 16 \).
