2. Divide this result by denominator of the fraction: 76/6 = 12.666666666667
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 76/2 = 38
   • 6/2 = 3
4. Which gives: 38/3

Since 38/3 is an improper fraction, the result could also be expressed as a mixed number: 12 2/3

How does it work?

The principle behind finding a fraction of a number, such as 4/6 of 19, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{4}{6}=\frac{x}{19}$ (where x represents 4/6 of 19)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $4\times 19=6x$
2. Which gives: $76=6x$
3. Divide both sides by 6 to isolate x: $\frac{76}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{76}{6}=x$ (or $\frac{38}{3}=x$)

Thus, 4/6 of 19 is equal to 38/3 (or 12.666666666667 in its decimal form).
