How does it work?

The principle behind finding a fraction of a number, such as 9/6 of 91, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{9}{6}=\frac{x}{91}$ (where x represents 9/6 of 91)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $9\times 91=6x$
2. Which gives: $819=6x$
3. Divide both sides by 6 to isolate x: $\frac{819}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{819}{6}=x$ (or $\frac{273}{2}=x$)

Thus, 9/6 of 91 is equal to 273/2 (or 136.5 in its decimal form).
