Let x be the number we're trying to find. We can set up the equation:

0.09x = 20

To solve for x, we divide both sides by 0.09:

x = 222.22

Rounding to the nearest hundredth gives us the final answer of:

x ≈ 222.22

So the best choice is A. To find the number, we can set up the equation: 
0.09x = 20 
Solving for x, we get: 
x = 222.22 
Rounding to the nearest hundredth, we get the closest answer choice as A) 222.22.
