2. Divide this result by denominator of the fraction: 344/6 = 57.333333333333
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 344/2 = 172
   • 6/2 = 3
4. Which gives: 172/3

How does it work?

The principle behind finding a fraction of a number, such as 4/6 of 86, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{4}{6}=\frac{x}{86}$ (where x represents 4/6 of 86)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $4\times 86=6x$
2. Which gives: $344=6x$
3. Divide both sides by 6 to isolate x: $\frac{344}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{344}{6}=x$ (or $\frac{172}{3}=x$)

Thus, 4/6 of 86 is equal to 172/3 (or 57.333333333333 in its decimal form).
