What is 5/10 of 37?

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 37? We'll show you a straightforward method to achieve that.

How to calculate 5/10 of 37?

  1. Multiply the whole number by the numerator of the fraction: 37 × 5 = 185
  2. Divide this result by denominator of the fraction: 185/10 = 18.5
  3. Simplify by dividing both the numerator and denominator by their GCD (5):
    • 185/5 = 37
    • 10/5 = 2
  4. Which gives: 37/2

Since 37/2 is an improper fraction, the result could also be expressed as a mixed number: 18 1/2

How does it work?

The principle behind finding a fraction of a number, such as 5/10 of 37, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 10 = x 37 (where x represents 5/10 of 37)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 37 = 10 x
  2. Which gives: 185 = 10 x
  3. Divide both sides by 10 to isolate x: 185 10 = 10 x 10
  4. Which gives the result: 185 10 = x (or 37 2 = x )

Thus, 5/10 of 37 is equal to 37/2 (or 18.5 in its decimal form).
