Asp.net i have three tables there.

I have seven chairs, to be divided proportionally among the three tables, without sawing any chair into pieces. How can it be done?

See below.









Borrow one chair, to make 8 chairs.
Put 1/2 of the chairs, namely 4, at the first table.
Put 1/2 of the remaining chairs, namely 2, at the second table.
Put 1/2 of the remaining chairs, namely 1, at the third table.
That puts 7 (4+2+1) chairs at the tables.
Return the borrowed chair.
Done!
