How does it work?

The principle behind finding a fraction of a number, such as 10/6 of 85, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{10}{6}=\frac{x}{85}$ (where x represents 10/6 of 85)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $10\times 85=6x$
2. Which gives: $850=6x$
3. Divide both sides by 6 to isolate x: $\frac{850}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{850}{6}=x$ (or $\frac{425}{3}=x$)

Thus, 10/6 of 85 is equal to 425/3 (or 141.66666666667 in its decimal form).
