What is 2/10 of 1?

How to calculate 2/10 of 1?

1. Multiply the whole number by the numerator of the fraction: 1 × 2 = 2
2. Divide this result by denominator of the fraction: 2/10 = 0.2
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 2/2 = 1
   • 10/2 = 5
4. Which gives: 1/5

How does it work?

The principle behind finding a fraction of a number, such as 2/10 of 1, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{10}=\frac{x}{1}$ (where x represents 2/10 of 1)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 1=10x$
2. Which gives: $2=10x$
3. Divide both sides by 10 to isolate x: $\frac{2}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{2}{10}=x$ (or $\frac{1}{5}=x$)

Thus, 2/10 of 1 is equal to 1/5 (or 0.2 in its decimal form).
