Sure, here's an example of step-by-step solutions for a math problem: Problem: Simplify the expression

\frac{4 x ^{3} y ^{2}}{2 x y}

. Solution: Step 1: Cancel out the common factor of

2

in the numerator and denominator:

\frac{4 x ^{3} y ^{2}}{2 x y} = \frac{2 \cdot 2 x ^{3} y ^{2}}{2 x y} = 2 x^{2} y

Step 2: Simplify further by combining like terms:

\frac{4 x ^{3} y ^{2}}{2 x y} = 2 x^{2} y
