1. Let's first restate the problem clearly to ensure understanding. 2. Step 5 involves applying the formula or rule that was introduced earlier. This step typically requires simplifying an expression or substituting values. 3. To clarify, if Step 5 involves simplifying an expression like $$\frac{a}{b} \times \frac{c}{d}$$, remember the rule: multiply numerators together and denominators together, so it becomes $$\frac{a \times c}{b \times d}$$. 4. If Step 5 involves solving for a variable, isolate the variable by performing inverse operations on both sides of the equation. 5. For example, if Step 5 is $$3x + 5 = 20$$, subtract 5 from both sides to get $$3x = 15$$, then divide both sides by 3 to find $$x = 5$$. 6. If you provide the exact expression or equation from Step 5, I can walk you through the specific calculations and reasoning. Please share the exact content of Step 5 for a detailed explanation.
