In your manufacturing apprenticeship, you are reviewing a module on algebraic operations used to calculate material tolerances. The module explicitly contrasts the operations $\frac{3a}{4} - \frac{8}{9}$ and $\frac{3a}{4} \cdot \frac{8}{9}$. Based on this example, what do you recall as the required procedure and final simplified result specifically for the subtraction problem?

In a technical skills workshop, you are reviewing how to perform operations on algebraic fractions for a material cost analysis. Based on the course example, match each operation involving the fractions $\frac{3a}{4}$ and $\frac{8}{9}$ with its correct procedural requirement and final simplified result.

In a technical skills workshop, you are reviewing how to perform operations on the algebraic fractions $\frac{3a}{4}$ and $\frac{8}{9}$. True or False: To correctly subtract these fractions, you must first find a least common denominator, but to multiply them, no common denominator is needed.

You are a quality control technician adjusting machinery settings. To ensure components fit correctly, you need to calculate the difference between two measurements: $\frac{3a}{4} - \frac{8}{9}$. Arrange the following steps of the subtraction process in the correct order as outlined in your technical training manual.
