How does it work?

The principle behind finding a fraction of a number, such as 1/10 of 54, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{1}{10}=\frac{x}{54}$ (where x represents 1/10 of 54)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $1\times 54=10x$
2. Which gives: $54=10x$
3. Divide both sides by 10 to isolate x: $\frac{54}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{54}{10}=x$ (or $\frac{27}{5}=x$)

Thus, 1/10 of 54 is equal to 27/5 (or 5.4 in its decimal form).
