What is 6/8 of 73?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 6/8 of 73? We'll show you a straightforward method to achieve that.

How to calculate 6/8 of 73?

  1. Multiply the whole number by the numerator of the fraction: 73 × 6 = 438
  2. Divide this result by denominator of the fraction: 438/8 = 54.75
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 438/2 = 219
    • 8/2 = 4
  4. Which gives: 219/4

Since 219/4 is an improper fraction, the result could also be expressed as a mixed number: 54 3/4

How does it work?

The principle behind finding a fraction of a number, such as 6/8 of 73, is rooted in the method of cross-multiplication.

Consider the following proportion: 6 8 = x 73 (where x represents 6/8 of 73)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 6 × 73 = 8 x
  2. Which gives: 438 = 8 x
  3. Divide both sides by 8 to isolate x: 438 8 = 8 x 8
  4. Which gives the result: 438 8 = x (or 219 4 = x )

Thus, 6/8 of 73 is equal to 219/4 (or 54.75 in its decimal form).
