3. Simplify by dividing both the numerator and denominator by their GCD (4):
   • 116/4 = 29
   • 8/4 = 2
4. Which gives: 29/2

How does it work?

The principle behind finding a fraction of a number, such as 2/8 of 58, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{8}=\frac{x}{58}$ (where x represents 2/8 of 58)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 58=8x$
2. Which gives: $116=8x$
3. Divide both sides by 8 to isolate x: $\frac{116}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{116}{8}=x$ (or $\frac{29}{2}=x$)

Thus, 2/8 of 58 is equal to 29/2 (or 14.5 in its decimal form).
