What is 10/1 of 72?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 10/1 of 72? We'll show you a straightforward method to achieve that.

How to calculate 10/1 of 72?

  1. Multiply the whole number by the numerator of the fraction: 72 × 10 = 720
  2. Divide this result by denominator of the fraction: 720/1 = 720

How does it work?

The principle behind finding a fraction of a number, such as 10/1 of 72, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 1 = x 72 (where x represents 10/1 of 72)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 72 = 1 x
  2. Which gives: 720 = 1 x
  3. Divide both sides by 1 to isolate x: 720 1 = 1 x 1
  4. Which gives the result: 720 1 = x

Thus, 10/1 of 72 is equal to 720/1 (or 720 in its decimal form).
