simplify: $\frac{-16x^{6}}{-4x^{9}}$
$\bigcirc$ $4x^{3}$
$\bigcirc$ $-4x^{3}$
$\bigcirc$ $-\frac{4}{x^{3}}$
$\bigcirc$ $\frac{4}{x^{3}}$

Explanation:

Step1: Simplify the coefficients

$\frac{-16}{-4} = 4$

Step2: Simplify the variable terms

$\frac{x^6}{x^9} = x^{6-9} = x^{-3} = \frac{1}{x^3}$

Step3: Combine the results

$4 \times \frac{1}{x^3} = \frac{4}{x^3}$

Answer:

$\boldsymbol{\frac{4}{x^3}}$ (matches the option: $\boldsymbol{\frac{4}{x^3}}$)
