How does it work?

The principle behind finding a fraction of a number, such as 7/7 of 23, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{7}{7}=\frac{x}{23}$ (where x represents 7/7 of 23)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $7\times 23=7x$
2. Which gives: $161=7x$
3. Divide both sides by 7 to isolate x: $\frac{161}{7}=\frac{7x}{7}$
4. Which gives the result: $\frac{161}{7}=x$ (or $\frac{23}{1}=x$)

Thus, 7/7 of 23 is equal to 23/1 (or 23 in its decimal form).
