3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 534/2 = 267
   • 4/2 = 2
4. Which gives: 267/2

How does it work?

The principle behind finding a fraction of a number, such as 6/4 of 89, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{6}{4}=\frac{x}{89}$ (where x represents 6/4 of 89)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $6\times 89=4x$
2. Which gives: $534=4x$
3. Divide both sides by 4 to isolate x: $\frac{534}{4}=\frac{4x}{4}$
4. Which gives the result: $\frac{534}{4}=x$ (or $\frac{267}{2}=x$)

Thus, 6/4 of 89 is equal to 267/2 (or 133.5 in its decimal form).
