What is 7/8 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 7/8 of 1? We'll show you a straightforward method to achieve that.

How to calculate 7/8 of 1?

  1. Multiply the whole number by the numerator of the fraction: 1 × 7 = 7
  2. Divide this result by denominator of the fraction: 7/8 = 0.875

How does it work?

The principle behind finding a fraction of a number, such as 7/8 of 1, is rooted in the method of cross-multiplication.

Consider the following proportion: 7 8 = x 1 (where x represents 7/8 of 1)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 7 × 1 = 8 x
  2. Which gives: 7 = 8 x
  3. Divide both sides by 8 to isolate x: 7 8 = 8 x 8
  4. Which gives the result: 7 8 = x

Thus, 7/8 of 1 is equal to 7/8 (or 0.875 in its decimal form).
