Question

Are a rational expression and its simplified forms equivalent? Provide mathematical examples to support your opinions.

Answer 1

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
