What is 2/6 of 90?

How to calculate 2/6 of 90?

1. Multiply the whole number by the numerator of the fraction: 90 × 2 = 180
2. Divide this result by denominator of the fraction: 180/6 = 30
3. Simplify by dividing both the numerator and denominator by their GCD (6):
   • 180/6 = 30
   • 6/6 = 1
4. Which gives: 30/1

How does it work?

The principle behind finding a fraction of a number, such as 2/6 of 90, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{6}=\frac{x}{90}$ (where x represents 2/6 of 90)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 90=6x$
2. Which gives: $180=6x$
3. Divide both sides by 6 to isolate x: $\frac{180}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{180}{6}=x$ (or $\frac{30}{1}=x$)

Thus, 2/6 of 90 is equal to 30/1 (or 30 in its decimal form).
