What is 6/9 of 23?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 6/9 of 23? We'll show you a straightforward method to achieve that.

How to calculate 6/9 of 23?

  1. Multiply the whole number by the numerator of the fraction: 23 × 6 = 138
  2. Divide this result by denominator of the fraction: 138/9 = 15.333333333333
  3. Simplify by dividing both the numerator and denominator by their GCD (3):
    • 138/3 = 46
    • 9/3 = 3
  4. Which gives: 46/3

Since 46/3 is an improper fraction, the result could also be expressed as a mixed number: 15 1/3

How does it work?

The principle behind finding a fraction of a number, such as 6/9 of 23, is rooted in the method of cross-multiplication.

Consider the following proportion: 6 9 = x 23 (where x represents 6/9 of 23)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 6 × 23 = 9 x
  2. Which gives: 138 = 9 x
  3. Divide both sides by 9 to isolate x: 138 9 = 9 x 9
  4. Which gives the result: 138 9 = x (or 46 3 = x )

Thus, 6/9 of 23 is equal to 46/3 (or 15.333333333333 in its decimal form).
