What is 6/2 of 39?

How to calculate 6/2 of 39?

1. Multiply the whole number by the numerator of the fraction: 39 × 6 = 234
2. Divide this result by denominator of the fraction: 234/2 = 117
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 234/2 = 117
   • 2/2 = 1
4. Which gives: 117/1

How does it work?

The principle behind finding a fraction of a number, such as 6/2 of 39, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{6}{2}=\frac{x}{39}$ (where x represents 6/2 of 39)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $6\times 39=2x$
2. Which gives: $234=2x$
3. Divide both sides by 2 to isolate x: $\frac{234}{2}=\frac{2x}{2}$
4. Which gives the result: $\frac{234}{2}=x$ (or $\frac{117}{1}=x$)

Thus, 6/2 of 39 is equal to 117/1 (or 117 in its decimal form).
