I am sure you have seen different “proofs” of this unequal equality: \( 1=2 \) .

Here is my version that would be based on the answers given to  this question

What fraction is shaded?

fraction one

here and here . One answer is 5/8, seeing the figure as something that is made up of 8 small squares, five of which have been shaded.  The other answer is 5/4, taking each bigger square as a unit (as a whole), seeing the figure as one whole and one fourth of that whole. This results in 1 and 1/4 that is the same as 5/4. Using the pizza metaphor, the first answer is like seeing the whole figure like a big pizza, the second answer is taking each four-piece square as a pizza. Basically, both interpretations are correct and just two different ways of numerically representing the same thing. Thus, we should have \( 5/8=5/4 \) , hence,\( 8=4 \). Now divide both side by 4 and voila, here it is:

\[ 1=2 \]
