Standard Operating Procedure for Fractional Cost Synthesis

A junior analyst at your logistics firm is attempting to merge two different departmental cost components expressed by the formula 35+x8\frac{3}{5} + \frac{x}{8}. The analyst is confused because their calculator is not 'merging' the terms into a single number, and they are considering reporting the result as 29x40\frac{29x}{40}. Write a brief instructional response for the analyst. In your response, describe the three-step procedure required to combine these fractions and specifically recall the algebraic rule regarding 'like terms' that explains why the result must remain as 24+5x40\frac{24 + 5x}{40} instead of 29x40\frac{29x}{40}.
