How does it work?

The principle behind finding a fraction of a number, such as 9/8 of 62, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{9}{8}=\frac{x}{62}$ (where x represents 9/8 of 62)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $9\times 62=8x$
2. Which gives: $558=8x$
3. Divide both sides by 8 to isolate x: $\frac{558}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{558}{8}=x$ (or $\frac{279}{4}=x$)

Thus, 9/8 of 62 is equal to 279/4 (or 69.75 in its decimal form).
