Answer 1

-75%

Explanation:

Given:

• Difference = -9
• Original = 12

Substitute the given values into the percent change formula:

`\begin{aligned}\sf Percent\:change & =\frac{\textsf{Difference between values}}{\textsf{Original value}} * 100\\\\& = (-9)/(12) * 100\\\\& = -(3)/(4) * 100\\\\& = -(300)/(4)\\\\& = -75\%\end{aligned}`

Therefore, the percent change is -75%.

This is a 75% decrease.
