Introduction


When dealing with complex fractions, it's essential to simplify them to make calculations easier and more manageable. In this article, we'll focus on simplifying the complex fraction 610x2÷610x360x2\frac{6}{10x^2} \div \frac{6}{10x^3-60x^2}. We'll break down the steps involved in simplifying this fraction and provide a clear explanation of each step.

Understanding Complex Fractions


A complex fraction is a fraction that contains one or more fractions in its numerator or denominator. In this case, we have a fraction with a fraction in the denominator. To simplify this fraction, we need to follow a specific set of steps.

Step 1: Invert and Multiply


The first step in simplifying a complex fraction is to invert the fraction in the denominator and multiply. This means that we'll multiply the fraction in the numerator by the reciprocal of the fraction in the denominator.

610x2÷610x360x2=610x2×10x360x26\frac{6}{10x^2} \div \frac{6}{10x^3-60x^2} = \frac{6}{10x^2} \times \frac{10x^3-60x^2}{6}

Step 2: Simplify the Expression


Now that we've inverted and multiplied, we can simplify the expression by canceling out any common factors.

610x2×10x360x26=1x2×10x360x21\frac{6}{10x^2} \times \frac{10x^3-60x^2}{6} = \frac{1}{x^2} \times \frac{10x^3-60x^2}{1}

Step 3: Factor the Expression


To simplify the expression further, we can factor out any common factors from the numerator.

1x2×10x360x21=1x2×10x2(x6)1\frac{1}{x^2} \times \frac{10x^3-60x^2}{1} = \frac{1}{x^2} \times \frac{10x^2(x-6)}{1}

Step 4: Cancel Out Common Factors


Now that we've factored the expression, we can cancel out any common factors between the numerator and denominator.

1x2×10x2(x6)1=10(x6)x2\frac{1}{x^2} \times \frac{10x^2(x-6)}{1} = \frac{10(x-6)}{x^2}

Step 5: Simplify the Expression


Finally, we can simplify the expression by canceling out any common factors.

10(x6)x2=10(x6)x2\frac{10(x-6)}{x^2} = \frac{10(x-6)}{x^2}

Conclusion


In this article, we've simplified the complex fraction 610x2÷610x360x2\frac{6}{10x^2} \div \frac{6}{10x^3-60x^2}. We've followed a step-by-step approach to simplify the fraction, including inverting and multiplying, simplifying the expression, factoring the expression, canceling out common factors, and simplifying the expression.

Final Answer


The final answer to the question is 10(x6)x2\boxed{\frac{10(x-6)}{x^2}}.

However, since the options are given in a different format, we can rewrite the final answer as:

x6x\boxed{x - \frac{6}{x}}

This can be further simplified to:

x6\boxed{x - 6}
