How does it work?

The principle behind finding a fraction of a number, such as 4/8 of 60, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{4}{8}=\frac{x}{60}$ (where x represents 4/8 of 60)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $4\times 60=8x$
2. Which gives: $240=8x$
3. Divide both sides by 8 to isolate x: $\frac{240}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{240}{8}=x$ (or $\frac{30}{1}=x$)

Thus, 4/8 of 60 is equal to 30/1 (or 30 in its decimal form).
