Answer 1

Dividing a quantity between 2 people in the ratio 1:1.  You get the same amount as me.

Dividing a quantity between 2 people in the ratio 0:1.  You get none, I get all of it.

Dividing a quantity between 2 people in the ratio 1:0.  You get all of it, I get none.

Actually the last two (1:0 and 0:1) are really the same thing because the problem doesn't define ahead of time which person/quantity is the first one and which is the second one.
