How does it work?

The principle behind finding a fraction of a number, such as 2/8 of 73, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{8}=\frac{x}{73}$ (where x represents 2/8 of 73)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 73=8x$
2. Which gives: $146=8x$
3. Divide both sides by 8 to isolate x: $\frac{146}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{146}{8}=x$ (or $\frac{73}{4}=x$)

Thus, 2/8 of 73 is equal to 73/4 (or 18.25 in its decimal form).
