What is 2/3 of 17?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 2/3 of 17? We'll show you a straightforward method to achieve that.

How to calculate 2/3 of 17?

  1. Multiply the whole number by the numerator of the fraction: 17 × 2 = 34
  2. Divide this result by denominator of the fraction: 34/3 = 11.333333333333

Since 34/3 is an improper fraction, the result could also be expressed as a mixed number: 11 1/3

How does it work?

The principle behind finding a fraction of a number, such as 2/3 of 17, is rooted in the method of cross-multiplication.

Consider the following proportion: 2 3 = x 17 (where x represents 2/3 of 17)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 2 × 17 = 3 x
  2. Which gives: 34 = 3 x
  3. Divide both sides by 3 to isolate x: 34 3 = 3 x 3
  4. Which gives the result: 34 3 = x

Thus, 2/3 of 17 is equal to 34/3 (or 11.333333333333 in its decimal form).
