What is 1/9 of 2?

How to calculate 1/9 of 2?

1. Multiply the whole number by the numerator of the fraction: 2 × 1 = 2
2. Divide this result by denominator of the fraction: 2/9 = 0.22222222222222

How does it work?

The principle behind finding a fraction of a number, such as 1/9 of 2, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{1}{9}=\frac{x}{2}$ (where x represents 1/9 of 2)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $1\times 2=9x$
2. Which gives: $2=9x$
3. Divide both sides by 9 to isolate x: $\frac{2}{9}=\frac{9x}{9}$
4. Which gives the result: $\frac{2}{9}=x$

Thus, 1/9 of 2 is equal to 2/9 (or 0.22222222222222 in its decimal form).
