What is 5/1 of 56?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 5/1 of 56? We'll show you a straightforward method to achieve that.

How to calculate 5/1 of 56?

  1. Multiply the whole number by the numerator of the fraction: 56 × 5 = 280
  2. Divide this result by denominator of the fraction: 280/1 = 280

How does it work?

The principle behind finding a fraction of a number, such as 5/1 of 56, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 1 = x 56 (where x represents 5/1 of 56)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 56 = 1 x
  2. Which gives: 280 = 1 x
  3. Divide both sides by 1 to isolate x: 280 1 = 1 x 1
  4. Which gives the result: 280 1 = x

Thus, 5/1 of 56 is equal to 280/1 (or 280 in its decimal form).
