Yes rational expression and its simplified forms are equivalent.
Rational expression are those that contain fractions.
Example:
25/50 is a rational expression but it is not yet in its simplest form.
25/50 ⇒ 5/10 ⇒ 1/2
1/2 is the simplest form of 25/50.
They are equivalent:
1/2 = 25/50
1*50 = 2*25
50 = 50
or
1/2 = 0.50
25/50 = 0.50
You need to multiply them 3-4 and get 12 so that's part of your answer
then you make it 12:9.

I believe the answer you're looking for is 30% or 3/10
To answer the question, let x be the cost of each hamburger, y be the cost of each medium fries, and z be the cost of each medium drink. The equations that are described in the problem are,
(Miller ) 4x + 3y = 18.69
(James) x + 2y + z = 8.66
(Steven) 2x + y + z = 10.27
Solving simultaneously for the values of the variables give x = 3.36, y = 1.75, and z = 1.8.
Thus, each hamburger costs $3.36. Each medium fries cost $1.75, and each drink costs $1.8.
