What is 10/2 of 50?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 10/2 of 50? We'll show you a straightforward method to achieve that.

How to calculate 10/2 of 50?

  1. Multiply the whole number by the numerator of the fraction: 50 × 10 = 500
  2. Divide this result by denominator of the fraction: 500/2 = 250
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 500/2 = 250
    • 2/2 = 1
  4. Which gives: 250/1

How does it work?

The principle behind finding a fraction of a number, such as 10/2 of 50, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 2 = x 50 (where x represents 10/2 of 50)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 50 = 2 x
  2. Which gives: 500 = 2 x
  3. Divide both sides by 2 to isolate x: 500 2 = 2 x 2
  4. Which gives the result: 500 2 = x (or 250 1 = x )

Thus, 10/2 of 50 is equal to 250/1 (or 250 in its decimal form).
