How does it work?

The principle behind finding a fraction of a number, such as 7/8 of 46, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{7}{8}=\frac{x}{46}$ (where x represents 7/8 of 46)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $7\times 46=8x$
2. Which gives: $322=8x$
3. Divide both sides by 8 to isolate x: $\frac{322}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{322}{8}=x$ (or $\frac{161}{4}=x$)

Thus, 7/8 of 46 is equal to 161/4 (or 40.25 in its decimal form).
