How does it work?

The principle behind finding a fraction of a number, such as 9/9 of 17, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{9}{9}=\frac{x}{17}$ (where x represents 9/9 of 17)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $9\times 17=9x$
2. Which gives: $153=9x$
3. Divide both sides by 9 to isolate x: $\frac{153}{9}=\frac{9x}{9}$
4. Which gives the result: $\frac{153}{9}=x$ (or $\frac{17}{1}=x$)

Thus, 9/9 of 17 is equal to 17/1 (or 17 in its decimal form).
