How does it work?

The principle behind finding a fraction of a number, such as 10/8 of 62, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{10}{8}=\frac{x}{62}$ (where x represents 10/8 of 62)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $10\times 62=8x$
2. Which gives: $620=8x$
3. Divide both sides by 8 to isolate x: $\frac{620}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{620}{8}=x$ (or $\frac{155}{2}=x$)

Thus, 10/8 of 62 is equal to 155/2 (or 77.5 in its decimal form).
