What is 5/5 of 54?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 5/5 of 54? We'll show you a straightforward method to achieve that.

How to calculate 5/5 of 54?

  1. Multiply the whole number by the numerator of the fraction: 54 × 5 = 270
  2. Divide this result by denominator of the fraction: 270/5 = 54
  3. Simplify by dividing both the numerator and denominator by their GCD (5):
    • 270/5 = 54
    • 5/5 = 1
  4. Which gives: 54/1

How does it work?

The principle behind finding a fraction of a number, such as 5/5 of 54, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 5 = x 54 (where x represents 5/5 of 54)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 54 = 5 x
  2. Which gives: 270 = 5 x
  3. Divide both sides by 5 to isolate x: 270 5 = 5 x 5
  4. Which gives the result: 270 5 = x (or 54 1 = x )

Thus, 5/5 of 54 is equal to 54/1 (or 54 in its decimal form).
