Check the picture below, so the green line is really the radius of the circle, and we know its center.
Well 12:2 is apples:loaves or A:L. So 12:2 is equivalent to 6:1 which is also equivalent to 30:5 or 30 apples:5 loaves
The number of permutations of the 4 different digits is:
The answer is 24 ways.
ANSWER: 12.56 units
