4/11+s=9/22 how to I find the answer to this

Well first, you want to subtract 4/11 from both sides of the equation. To do this, you must find the common denominator between 4/11 and 9/22. The common denominator is 22. This is how it should look:

4/11 + s = 9/22

8/22 + s = 9/22

-8/22 - 8/22

s = 1/22

First you have to subtract 4/11 from the variable side of the equation and the right side as well. Then you'll have s=9/22-8/22, so your answer is 1/22
