Answer:
The percent for 3 out of 12 is 25%
If the total number of games was 100, the win amount would need to be 25.
Step-by-step explanation:
3 out of 12 is a fraction - 3/12
3/12 = 0.25 which means 25% because 0.25 is 25% of 1.
Using the same percentage for 100 total games, you just multiply 100 by 0.25, the decimal version of the percentage.

Then, you can take the square root on both sides.
Not asked, but good to understand the procedure regardless.
Answer: 108 degrees
============================================================
Explanation:
Angle ABC is given to be 90 degrees. By the converse of Thales Theorem, we know that AC is a diameter of the circle.
If we draw a line from A to C, it will pass through the center of the circle.
Therefore, arc AC is 180 degrees as this is half the distance around the circle.
minor arc AD = 72
minor arc CD = x
(minor arc AD) + (minor arc CD) = arc AC
72+x = 180
72+x-72 = 180-72
x = 108
minor arc CD is 108 degrees
