To solve the proportion 725/77.5 = 23.2/a, you can cross-multiply and then solve for the unknown variable. Cross-multiplying gives you 725 * a = 77.5 * 23.2. Simplifying this equation, you get 725a = 1798. The next step is to isolate the variable by dividing both sides of the equation by 725. This gives you a = 1798/725. Simplifying further, you find that a is approximately equal to 2.48.
