What is 6/2 of 85?

How to calculate 6/2 of 85?

1. Multiply the whole number by the numerator of the fraction: 85 × 6 = 510
2. Divide this result by denominator of the fraction: 510/2 = 255
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 510/2 = 255
   • 2/2 = 1
4. Which gives: 255/1

How does it work?

The principle behind finding a fraction of a number, such as 6/2 of 85, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{6}{2}=\frac{x}{85}$ (where x represents 6/2 of 85)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $6\times 85=2x$
2. Which gives: $510=2x$
3. Divide both sides by 2 to isolate x: $\frac{510}{2}=\frac{2x}{2}$
4. Which gives the result: $\frac{510}{2}=x$ (or $\frac{255}{1}=x$)

Thus, 6/2 of 85 is equal to 255/1 (or 255 in its decimal form).
