We are asked to make an algebraic expression for the given situation. The key phrase is ... divided by ... This tells us that we should divide two things.
.../...
The two terms that we are dividing are 22 and a number s. Since 22 comes first in the statement, it should be in the numerator side of the fraction.
22/...
When we say a number s, this is telling us that an arbitrary number will be denoted by s. So, by placing s in the denominator, we can complete our expression.
22/s
Note that this is only one of multiple ways to algebraically express the given statement.
