The discussion centers on comparing two fractions, A and B, both with large numerators and denominators. Fraction A simplifies to 1 minus a small value related to the denominator, while fraction B simplifies similarly but with a different small value. The calculations reveal that fraction B is greater than fraction A. Participants express admiration for the mathematical elegance of the solution. The conclusion is that B is the larger fraction.

Which of the fractions is greater?

$$A=\frac{\overbrace{333\cdots331}^{ \large{\text{2012 pieces}}}}{\underbrace{333\cdots334}_{ \large{\text{2012 pieces}}}}$$

or

$$B=\frac{\overbrace{222\cdots221}^{ \large{\text{2012 pieces}}}}{\underbrace{222\cdots223}_{ \large{\text{2012 pieces}}}}$$?

A=1-\frac{1}{33...34/3}=1-\frac{1}{111..11 +\frac{1}{3}}

B=1-\frac{1}{22...23/2}=1-\frac{1}{111..11+\frac{1}{2}}

B is greater.
 
Very beautiful and impressive, M R!(Clapping)
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
