2. Divide this result by denominator of the fraction: 146/4 = 36.5
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 146/2 = 73
   • 4/2 = 2
4. Which gives: 73/2

How does it work?

The principle behind finding a fraction of a number, such as 2/4 of 73, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{4}=\frac{x}{73}$ (where x represents 2/4 of 73)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 73=4x$
2. Which gives: $146=4x$
3. Divide both sides by 4 to isolate x: $\frac{146}{4}=\frac{4x}{4}$
4. Which gives the result: $\frac{146}{4}=x$ (or $\frac{73}{2}=x$)

Thus, 2/4 of 73 is equal to 73/2 (or 36.5 in its decimal form).
