What is 8/1 of 63?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 8/1 of 63? We'll show you a straightforward method to achieve that.

How to calculate 8/1 of 63?

  1. Multiply the whole number by the numerator of the fraction: 63 × 8 = 504
  2. Divide this result by denominator of the fraction: 504/1 = 504

How does it work?

The principle behind finding a fraction of a number, such as 8/1 of 63, is rooted in the method of cross-multiplication.

Consider the following proportion: 8 1 = x 63 (where x represents 8/1 of 63)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 8 × 63 = 1 x
  2. Which gives: 504 = 1 x
  3. Divide both sides by 1 to isolate x: 504 1 = 1 x 1
  4. Which gives the result: 504 1 = x

Thus, 8/1 of 63 is equal to 504/1 (or 504 in its decimal form).
