Solution by Steps
step 1
Start by rewriting the given expression: 2x3y7y3÷x214y \frac{2 x^{3} y}{7 y^{3}} \div \frac{x^{2}}{14 y} as a multiplication problem by taking the reciprocal of the second fraction: 2x3y7y3×14yx2 \frac{2 x^{3} y}{7 y^{3}} \times \frac{14 y}{x^{2}}
step 2
Simplify the expression by multiplying the numerators and the denominators: 2x3y14y7y3x2=28x3y27y3x2 \frac{2 x^{3} y \cdot 14 y}{7 y^{3} \cdot x^{2}} = \frac{28 x^{3} y^{2}}{7 y^{3} x^{2}}
step 3
Simplify the fraction by canceling common factors in the numerator and the denominator: 28x3y27y3x2=4xy2y=4xy \frac{28 x^{3} y^{2}}{7 y^{3} x^{2}} = \frac{4 x y^{2}}{y} = 4 x y
