How does it work?

The principle behind finding a fraction of a number, such as 2/10 of 58, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{10}=\frac{x}{58}$ (where x represents 2/10 of 58)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 58=10x$
2. Which gives: $116=10x$
3. Divide both sides by 10 to isolate x: $\frac{116}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{116}{10}=x$ (or $\frac{58}{5}=x$)

Thus, 2/10 of 58 is equal to 58/5 (or 11.6 in its decimal form).
