What is 10/6 of 18?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 10/6 of 18? We'll show you a straightforward method to achieve that.

How to calculate 10/6 of 18?

  1. Multiply the whole number by the numerator of the fraction: 18 × 10 = 180
  2. Divide this result by denominator of the fraction: 180/6 = 30
  3. Simplify by dividing both the numerator and denominator by their GCD (6):
    • 180/6 = 30
    • 6/6 = 1
  4. Which gives: 30/1

How does it work?

The principle behind finding a fraction of a number, such as 10/6 of 18, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 6 = x 18 (where x represents 10/6 of 18)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 18 = 6 x
  2. Which gives: 180 = 6 x
  3. Divide both sides by 6 to isolate x: 180 6 = 6 x 6
  4. Which gives the result: 180 6 = x (or 30 1 = x )

Thus, 10/6 of 18 is equal to 30/1 (or 30 in its decimal form).
