What is 2/10 of 2?

How to calculate 2/10 of 2?

1. Multiply the whole number by the numerator of the fraction: 2 × 2 = 4
2. Divide this result by denominator of the fraction: 4/10 = 0.4
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 4/2 = 2
   • 10/2 = 5
4. Which gives: 2/5

How does it work?

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

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

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

Thus, 2/10 of 2 is equal to 2/5 (or 0.4 in its decimal form).
