How does it work?

The principle behind finding a fraction of a number, such as 7/2 of 74, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{7}{2}=\frac{x}{74}$ (where x represents 7/2 of 74)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $7\times 74=2x$
2. Which gives: $518=2x$
3. Divide both sides by 2 to isolate x: $\frac{518}{2}=\frac{2x}{2}$
4. Which gives the result: $\frac{518}{2}=x$ (or $\frac{259}{1}=x$)

Thus, 7/2 of 74 is equal to 259/1 (or 259 in its decimal form).
