How does it work?

The principle behind finding a fraction of a number, such as 9/7 of 35, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{9}{7}=\frac{x}{35}$ (where x represents 9/7 of 35)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $9\times 35=7x$
2. Which gives: $315=7x$
3. Divide both sides by 7 to isolate x: $\frac{315}{7}=\frac{7x}{7}$
4. Which gives the result: $\frac{315}{7}=x$ (or $\frac{45}{1}=x$)

Thus, 9/7 of 35 is equal to 45/1 (or 45 in its decimal form).
