How does it work?

The principle behind finding a fraction of a number, such as 3/6 of 69, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{3}{6}=\frac{x}{69}$ (where x represents 3/6 of 69)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $3\times 69=6x$
2. Which gives: $207=6x$
3. Divide both sides by 6 to isolate x: $\frac{207}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{207}{6}=x$ (or $\frac{69}{2}=x$)

Thus, 3/6 of 69 is equal to 69/2 (or 34.5 in its decimal form).
