2. Divide this result by denominator of the fraction: 117/3 = 39
3. Simplify by dividing both the numerator and denominator by their GCD (3):
   • 117/3 = 39
   • 3/3 = 1
4. Which gives: 39/1

How does it work?

The principle behind finding a fraction of a number, such as 3/3 of 39, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{3}{3}=\frac{x}{39}$ (where x represents 3/3 of 39)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $3\times 39=3x$
2. Which gives: $117=3x$
3. Divide both sides by 3 to isolate x: $\frac{117}{3}=\frac{3x}{3}$
4. Which gives the result: $\frac{117}{3}=x$ (or $\frac{39}{1}=x$)

Thus, 3/3 of 39 is equal to 39/1 (or 39 in its decimal form).
