Jul 1, 2018

-9.0bar9%

#### Explanation:

If the original number is $55$, and the new number is $50$, we can see that the number has been decreased by $55 - 50 = 5$.

Therefore, the percent decrease is:

5/55*100%=9.0bar9%

In order to write a decrease, I put a $- \text{ve}$ sign in front, indicating that there was a reduction from the original number.
