8 days
Step-by-step explanation:
Set up a fraction. Let "x" be the variable.
[tex]\frac{-2.25}{1}=-\frac{18}{x}[/tex]
Step 1: Apply fraction cross multiply
[tex]\left(-2.25\right)x=-1\cdot \:18[/tex]
Step 2: Simplify
[tex]-2.25x=-18[/tex]
Step 3: Divide both sides by [tex]-2.25[/tex]
[tex]\frac{-2.25x}{-2.25}=\frac{-18}{-2.25}[/tex]
Step 4: Simplify
[tex]x=8[/tex]
