What is 6/10 of 31?

How to calculate 6/10 of 31?

1. Multiply the whole number by the numerator of the fraction: 31 × 6 = 186
2. Divide this result by denominator of the fraction: 186/10 = 18.6
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 186/2 = 93
   • 10/2 = 5
4. Which gives: 93/5

Since 93/5 is an improper fraction, the result could also be expressed as a mixed number: 18 3/5

How does it work?

The principle behind finding a fraction of a number, such as 6/10 of 31, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{6}{10}=\frac{x}{31}$ (where x represents 6/10 of 31)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $6\times 31=10x$
2. Which gives: $186=10x$
3. Divide both sides by 10 to isolate x: $\frac{186}{10}=\frac{10x}{10}$
4. Which gives the result: $\frac{186}{10}=x$ (or $\frac{93}{5}=x$)

Thus, 6/10 of 31 is equal to 93/5 (or 18.6 in its decimal form).
