How does it work?

The principle behind finding a fraction of a number, such as 3/9 of 93, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{3}{9}=\frac{x}{93}$ (where x represents 3/9 of 93)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $3\times 93=9x$
2. Which gives: $279=9x$
3. Divide both sides by 9 to isolate x: $\frac{279}{9}=\frac{9x}{9}$
4. Which gives the result: $\frac{279}{9}=x$ (or $\frac{31}{1}=x$)

Thus, 3/9 of 93 is equal to 31/1 (or 31 in its decimal form).
