How does it work?

The principle behind finding a fraction of a number, such as 2/1 of 86, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{1}=\frac{x}{86}$ (where x represents 2/1 of 86)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 86=1x$
2. Which gives: $172=1x$
3. Divide both sides by 1 to isolate x: $\frac{172}{1}=\frac{1x}{1}$
4. Which gives the result: $\frac{172}{1}=x$

Thus, 2/1 of 86 is equal to 172/1 (or 172 in its decimal form).
