   • 6/6 = 1
4. Which gives: 19/1

How does it work?

The principle behind finding a fraction of a number, such as 3/6 of 38, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{3}{6}=\frac{x}{38}$ (where x represents 3/6 of 38)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $3\times 38=6x$
2. Which gives: $114=6x$
3. Divide both sides by 6 to isolate x: $\frac{114}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{114}{6}=x$ (or $\frac{19}{1}=x$)

Thus, 3/6 of 38 is equal to 19/1 (or 19 in its decimal form).
