What is 2/10 of 11?

How to calculate 2/10 of 11?

1. Multiply the whole number by the numerator of the fraction: 11 × 2 = 22
2. Divide this result by denominator of the fraction: 22/10 = 2.2
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 22/2 = 11
   • 10/2 = 5
4. Which gives: 11/5

Since 11/5 is an improper fraction, the result could also be expressed as a mixed number: 2 1/5

How does it work?

The principle behind finding a fraction of a number, such as 2/10 of 11, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{10}=\frac{x}{11}$ (where x represents 2/10 of 11)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 11=10x$
2. Which gives: $22=10x$
3. Divide both sides by 10 to isolate x: $\frac{22}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{22}{10}=x$ (or $\frac{11}{5}=x$)

Thus, 2/10 of 11 is equal to 11/5 (or 2.2 in its decimal form).
