I need to lower the percentage of the fourth number from 75% to %66 AND have the remaining percentages still add up to 100%.
So this is where I am:

0.66

Not very good. How do I determine what the percentages for the other numbers should be? I know the answer is very simple, but I’m drawing a blank. PS: this is not homework!
Do you mean you want the “extra” spread evenly among the remaining numbers?
Then is would just involve adding 1.3% to the other numbers. (1.3% is the 9% you are removing from the 75% to get to 66% divided among the other 7 values)
If you want to change only the fourth number, while leaving all the other numbers the same, so that the fourth number is now 66% of the total instead of 75% (and the new total, of course, will no longer be 200), the fourth number needs to be 95.94334509.
Here’s how I got that:
Call the fourth number x. The other numbers add up to 49.42535959, so the total will be x + 49.42535959.
You want the fourth number to be 66% of the total: this means you want x = .66(x + 49.42535959).
First, let me point out that the numbers you posted aren’t percentages. They’re percentages divided by 100, so they range from 0.0-1.0, not 0-100.
The question you ask is sort of up to interpretation. As I understand it, you should do the following:
When you change 150.5746404 to be 66% of the total, 200, you get 132. Now that means that the rest of the numbers now take up 34%, not 25%. That means you’ll want to increase each number by a factor of 34/25, or 1.36
