What is 5/8 of 74?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 5/8 of 74? We'll show you a straightforward method to achieve that.

How to calculate 5/8 of 74?

  1. Multiply the whole number by the numerator of the fraction: 74 × 5 = 370
  2. Divide this result by denominator of the fraction: 370/8 = 46.25
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 370/2 = 185
    • 8/2 = 4
  4. Which gives: 185/4

Since 185/4 is an improper fraction, the result could also be expressed as a mixed number: 46 1/4

How does it work?

The principle behind finding a fraction of a number, such as 5/8 of 74, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 8 = x 74 (where x represents 5/8 of 74)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 74 = 8 x
  2. Which gives: 370 = 8 x
  3. Divide both sides by 8 to isolate x: 370 8 = 8 x 8
  4. Which gives the result: 370 8 = x (or 185 4 = x )

Thus, 5/8 of 74 is equal to 185/4 (or 46.25 in its decimal form).
