How does it work?

The principle behind finding a fraction of a number, such as 8/6 of 86, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{8}{6}=\frac{x}{86}$ (where x represents 8/6 of 86)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $8\times 86=6x$
2. Which gives: $688=6x$
3. Divide both sides by 6 to isolate x: $\frac{688}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{688}{6}=x$ (or $\frac{344}{3}=x$)

Thus, 8/6 of 86 is equal to 344/3 (or 114.66666666667 in its decimal form).
