What is 5/10 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 5/10 of 73? We'll show you a straightforward method to achieve that.

How to calculate 5/10 of 73?

  1. Multiply the whole number by the numerator of the fraction: 73 × 5 = 365
  2. Divide this result by denominator of the fraction: 365/10 = 36.5
  3. Simplify by dividing both the numerator and denominator by their GCD (5):
    • 365/5 = 73
    • 10/5 = 2
  4. Which gives: 73/2

Since 73/2 is an improper fraction, the result could also be expressed as a mixed number: 36 1/2

How does it work?

The principle behind finding a fraction of a number, such as 5/10 of 73, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 10 = x 73 (where x represents 5/10 of 73)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 73 = 10 x
  2. Which gives: 365 = 10 x
  3. Divide both sides by 10 to isolate x: 365 10 = 10 x 10
  4. Which gives the result: 365 10 = x (or 73 2 = x )

Thus, 5/10 of 73 is equal to 73/2 (or 36.5 in its decimal form).
