100 is smaller than 110 by x%

9.09

Step-by-step explanation:

100 is 90.91% of 110 so subtract 90.91% from 100% and you get your answer

Step-by-step explanation:

110 * x/100 = 100 Multiply both sides by 100

110 * x = 100*100 Combine the right.

110 * x = 10000 Divide by 110

x = 10000/110

x = 90.9 %

But that is not the answer you want. It is asking by what % if 100 smaller than 110

The answer is 100 - 90.9 = 9.09

So if you take 9.09 / 100 * 110 you should get the number that you subtract from 110 to get 100.
