Okay kiddo, let me try to explain linear-fractional programming in a way that is easy for you to understand.
Linear-fractional programming is like a really hard math puzzle where you have to find the answers by using numbers and symbols. It's like a game where you try to get the highest score by following certain rules.
Imagine that you are at a candy store and you have a certain amount of money to spend. You want to buy as many candies as possible but you also have to make sure you don't spend more money than you have. This is where linear-fractional programming comes in.
In linear-fractional programming, you have a bunch of equations that tell you how much of each candy costs and how much money you have. You have to use these equations to figure out how many candies of each type you can buy without spending more than you have.
It's kind of like a math puzzle because you have to figure out the right combination of candies to buy that will give you the most candy without going over your budget.
Linear-fractional programming is used in lots of different fields, like economics and engineering, because it helps people make decisions based on mathematical models. It's a tricky concept, but if you practice and work hard, you can become very good at it!
