What is 10/3 of 75?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 10/3 of 75? We'll show you a straightforward method to achieve that.

How to calculate 10/3 of 75?

  1. Multiply the whole number by the numerator of the fraction: 75 × 10 = 750
  2. Divide this result by denominator of the fraction: 750/3 = 250
  3. Simplify by dividing both the numerator and denominator by their GCD (3):
    • 750/3 = 250
    • 3/3 = 1
  4. Which gives: 250/1

How does it work?

The principle behind finding a fraction of a number, such as 10/3 of 75, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 3 = x 75 (where x represents 10/3 of 75)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 75 = 3 x
  2. Which gives: 750 = 3 x
  3. Divide both sides by 3 to isolate x: 750 3 = 3 x 3
  4. Which gives the result: 750 3 = x (or 250 1 = x )

Thus, 10/3 of 75 is equal to 250/1 (or 250 in its decimal form).
