i struggle a bit with ratio and fraction calculations, so im just looking for some explanation for dummies of this one.
in linear programming, i have a ratio constraint of 6:5, of product A to product B.
The proper way, i believe, to insert this into a linear program is: 5A - 6B >= 0
that is, 5XA - 5XB, must be greater or equal to zero for constraint of 6:5 to be sufficed.
first of all, is this correct? and if so, can someone try to explain to me how this works? , ie how does flipping the ratio (6:5 , A to b, becomes 5xa - 6xb) cancel the other out and equate to zero or great when constraint is met?
a written example with calculation should help me visualize this, just absolutely struggling to get my head around it.
thanks guys! any help is much appreciated.
