One professor was invited to the militia to read a lecture on the fragments to the menta... Since the menta did not want or could not understand anything, then when it came to the practical part and the professor asked what was more - "3/5" or "6/7", no one replied.



But the professor found a way - he formulated the question differently:

What is more: 3 bottles of vodka for 5 people or 6 bottles for 7 people?

The mentions immediately answered that 6/7 is more.
