The principle behind finding a fraction of a number, such as 3/9 of 73, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{3}{9}=\frac{x}{73}$ (where x represents 3/9 of 73)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $3\times 73=9x$
2. Which gives: $219=9x$
3. Divide both sides by 9 to isolate x: $\frac{219}{9}=\frac{9x}{9}$
4. Which gives the result: $\frac{219}{9}=x$ (or $\frac{73}{3}=x$)

Thus, 3/9 of 73 is equal to 73/3 (or 24.333333333333 in its decimal form).
