The ratio described measures profitability relative to the amount of revenue generated. By taking profit and dividing it by revenue, you’re seeing what portion of every dollar of revenue actually becomes profit. This is commonly called the net profit margin: a higher margin means more efficient conversion of revenue into profit.

Why this fits: profit divided by revenue directly expresses profit per unit of revenue, which is exactly what “profit-to-revenue” (or profit margin) indicates.

Why the others don’t fit: dividing profit by equity would show return on equity, relating profit to owners’ investment rather than revenue. Revenue divided by profit would be the inverse of the margin, not the intended measure. Overhead divided by revenue looks at cost efficiency of overhead, not the profit portion.
