What is 6/1 of 13?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 6/1 of 13? We'll show you a straightforward method to achieve that.

How to calculate 6/1 of 13?

  1. Multiply the whole number by the numerator of the fraction: 13 × 6 = 78
  2. Divide this result by denominator of the fraction: 78/1 = 78

How does it work?

The principle behind finding a fraction of a number, such as 6/1 of 13, is rooted in the method of cross-multiplication.

Consider the following proportion: 6 1 = x 13 (where x represents 6/1 of 13)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 6 × 13 = 1 x
  2. Which gives: 78 = 1 x
  3. Divide both sides by 1 to isolate x: 78 1 = 1 x 1
  4. Which gives the result: 78 1 = x

Thus, 6/1 of 13 is equal to 78/1 (or 78 in its decimal form).
