What is 2/10 of 61?

How to calculate 2/10 of 61?

1. Multiply the whole number by the numerator of the fraction: 61 × 2 = 122
2. Divide this result by denominator of the fraction: 122/10 = 12.2
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 122/2 = 61
   • 10/2 = 5
4. Which gives: 61/5

Since 61/5 is an improper fraction, the result could also be expressed as a mixed number: 12 1/5

How does it work?

The principle behind finding a fraction of a number, such as 2/10 of 61, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{10}=\frac{x}{61}$ (where x represents 2/10 of 61)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 61=10x$
2. Which gives: $122=10x$
3. Divide both sides by 10 to isolate x: $\frac{122}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{122}{10}=x$ (or $\frac{61}{5}=x$)

Thus, 2/10 of 61 is equal to 61/5 (or 12.2 in its decimal form).
