Simplify the rational expression \( \frac{2x^2y^3}{4x^3y} \)

Step 1 ：The given expression is \( \frac{2x^2y^3}{4x^3y} \)

Step 2 ：First, we can cancel out the common factor between the numerator and the denominator. The common factors are 2, \(x^2\), and \(y\)

Step 3 ：After cancelling out the common factors, we get \( \frac{2x^2y^3}{4x^3y} = \frac{y^2}{2x} \)
