What is 9/5 of 6?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 9/5 of 6? We'll show you a straightforward method to achieve that.

How to calculate 9/5 of 6?

  1. Multiply the whole number by the numerator of the fraction: 6 × 9 = 54
  2. Divide this result by denominator of the fraction: 54/5 = 10.8

Since 54/5 is an improper fraction, the result could also be expressed as a mixed number: 10 4/5

How does it work?

The principle behind finding a fraction of a number, such as 9/5 of 6, is rooted in the method of cross-multiplication.

Consider the following proportion: 9 5 = x 6 (where x represents 9/5 of 6)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 9 × 6 = 5 x
  2. Which gives: 54 = 5 x
  3. Divide both sides by 5 to isolate x: 54 5 = 5 x 5
  4. Which gives the result: 54 5 = x

Thus, 9/5 of 6 is equal to 54/5 (or 10.8 in its decimal form).
