How does it work?

The principle behind finding a fraction of a number, such as 7/10 of 7, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{7}{10}=\frac{x}{7}$ (where x represents 7/10 of 7)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $7\times 7=10x$
2. Which gives: $49=10x$
3. Divide both sides by 10 to isolate x: $\frac{49}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{49}{10}=x$

Thus, 7/10 of 7 is equal to 49/10 (or 4.9 in its decimal form).
