What is 4/4 of 98?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 4/4 of 98? We'll show you a straightforward method to achieve that.

How to calculate 4/4 of 98?

  1. Multiply the whole number by the numerator of the fraction: 98 × 4 = 392
  2. Divide this result by denominator of the fraction: 392/4 = 98
  3. Simplify by dividing both the numerator and denominator by their GCD (4):
    • 392/4 = 98
    • 4/4 = 1
  4. Which gives: 98/1

How does it work?

The principle behind finding a fraction of a number, such as 4/4 of 98, is rooted in the method of cross-multiplication.

Consider the following proportion: 4 4 = x 98 (where x represents 4/4 of 98)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 4 × 98 = 4 x
  2. Which gives: 392 = 4 x
  3. Divide both sides by 4 to isolate x: 392 4 = 4 x 4
  4. Which gives the result: 392 4 = x (or 98 1 = x )

Thus, 4/4 of 98 is equal to 98/1 (or 98 in its decimal form).
