As a data technician in a corporate finance department, you are tasked with simplifying a complex forecasting model. The model is represented by a formula containing multiple rational expressions linked by both multiplication and division. To ensure accuracy before coding the formula into the system, recall the correct order of algebraic steps required to simplify the overall expression.

You are a junior logistics analyst tasked with simplifying an efficiency ratio for a shipping company. The ratio is expressed as the following formula:

$\frac{3x-6}{4x-4} \cdot \frac{x^2+2x-3}{x^2-3x-10} \div \frac{2x+12}{8x+16}$

Recall the standard algebraic procedure for operating on multiple rational expressions. What is the correct first step you should take to begin simplifying this formula?

As a Logistics Data Analyst, you are auditing the manual calculation steps for a 'Storage Efficiency Index.' The formula used in the system is: ${}\frac{3x-6}{4x-4} \cdot \frac{x^2+2x-3}{x^2-3x-10} \div \frac{2x+12}{8x+16}$. Match the specific component or phase of the formula simplification with the correct algebraic action required to process it.

As a data technician at a logistics firm, you are auditing a resource allocation formula involving multiple rational expressions: $\frac{3x-6}{4x-4} \cdot \frac{x^2+2x-3}{x^2-3x-10} \div \frac{2x+12}{8x+16}$. To begin simplifying this formula, the standard algebraic procedure requires you to change the division sign to multiplication and replace the divisor, $\frac{2x+12}{8x+16}$, with its ________.
