What is 5/8 of 1?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 5/8 of 1? We'll show you a straightforward method to achieve that.

How to calculate 5/8 of 1?

  1. Multiply the whole number by the numerator of the fraction: 1 × 5 = 5
  2. Divide this result by denominator of the fraction: 5/8 = 0.625

How does it work?

The principle behind finding a fraction of a number, such as 5/8 of 1, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 8 = x 1 (where x represents 5/8 of 1)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 1 = 8 x
  2. Which gives: 5 = 8 x
  3. Divide both sides by 8 to isolate x: 5 8 = 8 x 8
  4. Which gives the result: 5 8 = x

Thus, 5/8 of 1 is equal to 5/8 (or 0.625 in its decimal form).
