How does it work?

The principle behind finding a fraction of a number, such as 1/8 of 64, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{1}{8}=\frac{x}{64}$ (where x represents 1/8 of 64)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $1\times 64=8x$
2. Which gives: $64=8x$
3. Divide both sides by 8 to isolate x: $\frac{64}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{64}{8}=x$ (or $\frac{8}{1}=x$)

Thus, 1/8 of 64 is equal to 8/1 (or 8 in its decimal form).
