Answer for screen readers
The number is $-72$.
Steps to Solve
- Define the unknown number
Let $x$ be the unknown number we are trying to find.
- Set up the equation
The problem states that when $x$ is divided by -9, the result is 8. We can write this as an equation: $$ \frac{x}{-9} = 8 $$
- Solve for $x$
To isolate $x$, we multiply both sides of the equation by -9: $$ \frac{x}{-9} \times -9 = 8 \times -9 $$ $$ x = -72 $$
The number is $-72$.
