How does it work?

The principle behind finding a fraction of a number, such as 2/8 of 68, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{8}=\frac{x}{68}$ (where x represents 2/8 of 68)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 68=8x$
2. Which gives: $136=8x$
3. Divide both sides by 8 to isolate x: $\frac{136}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{136}{8}=x$ (or $\frac{17}{1}=x$)

Thus, 2/8 of 68 is equal to 17/1 (or 17 in its decimal form).
