What is 5/4 of 88?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 5/4 of 88? We'll show you a straightforward method to achieve that.

How to calculate 5/4 of 88?

  1. Multiply the whole number by the numerator of the fraction: 88 × 5 = 440
  2. Divide this result by denominator of the fraction: 440/4 = 110
  3. Simplify by dividing both the numerator and denominator by their GCD (4):
    • 440/4 = 110
    • 4/4 = 1
  4. Which gives: 110/1

How does it work?

The principle behind finding a fraction of a number, such as 5/4 of 88, is rooted in the method of cross-multiplication.

Consider the following proportion: 5 4 = x 88 (where x represents 5/4 of 88)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 5 × 88 = 4 x
  2. Which gives: 440 = 4 x
  3. Divide both sides by 4 to isolate x: 440 4 = 4 x 4
  4. Which gives the result: 440 4 = x (or 110 1 = x )

Thus, 5/4 of 88 is equal to 110/1 (or 110 in its decimal form).
