The principle behind finding a fraction of a number, such as 8/8 of 87, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{8}{8}=\frac{x}{87}$ (where x represents 8/8 of 87)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $8\times 87=8x$
2. Which gives: $696=8x$
3. Divide both sides by 8 to isolate x: $\frac{696}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{696}{8}=x$ (or $\frac{87}{1}=x$)

Thus, 8/8 of 87 is equal to 87/1 (or 87 in its decimal form).
