Answer:
11.11111%
11 1/9% decrease
Explanation:
We know that this is a decrease since the number goes from a higher amount to a lower amount.
To find the percent decreases, we take the original amount and subtract the new amount
3600-3200 = 400
Divide this by the original amount
400/3600
.11111111111
Multiply by 100% to get to percent form
11.11111%
We know that .1111111 is 1/9
11 1/9%
