What is 9/1 of 36?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 9/1 of 36? We'll show you a straightforward method to achieve that.

How to calculate 9/1 of 36?

  1. Multiply the whole number by the numerator of the fraction: 36 × 9 = 324
  2. Divide this result by denominator of the fraction: 324/1 = 324

How does it work?

The principle behind finding a fraction of a number, such as 9/1 of 36, is rooted in the method of cross-multiplication.

Consider the following proportion: 9 1 = x 36 (where x represents 9/1 of 36)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 9 × 36 = 1 x
  2. Which gives: 324 = 1 x
  3. Divide both sides by 1 to isolate x: 324 1 = 1 x 1
  4. Which gives the result: 324 1 = x

Thus, 9/1 of 36 is equal to 324/1 (or 324 in its decimal form).
