E) 0.40 < x < 0.45

Given: x = 49.5 percent of 11/23 of 0.996
In other words, x = (49.5/100)(11/23)(0.996)

Notice that 49.5/100 is a little bit less than 0.5
And 11/23 is a bit less than 0.5. Aside: we know this because 11/22 = 0.5, so 11/23 is a bit less than 0.5
And 0.996 is a bit less than 1

So, x = (little bit less than 0.5)(bit less than 0.5)(a bit less than 1)
We know that (0.5)(0.5)(1) = 0.25
So, (little bit less than 0.5)(bit less than 0.5)(a bit less than 1) = a bit less than 0.25
