How does it work?

The principle behind finding a fraction of a number, such as 4/4 of 43, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{4}{4}=\frac{x}{43}$ (where x represents 4/4 of 43)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $4\times 43=4x$
2. Which gives: $172=4x$
3. Divide both sides by 4 to isolate x: $\frac{172}{4}=\frac{4x}{4}$
4. Which gives the result: $\frac{172}{4}=x$ (or $\frac{43}{1}=x$)

Thus, 4/4 of 43 is equal to 43/1 (or 43 in its decimal form).
