What is 3/2 of 63?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 3/2 of 63? We'll show you a straightforward method to achieve that.

How to calculate 3/2 of 63?

  1. Multiply the whole number by the numerator of the fraction: 63 × 3 = 189
  2. Divide this result by denominator of the fraction: 189/2 = 94.5

Since 189/2 is an improper fraction, the result could also be expressed as a mixed number: 94 1/2

How does it work?

The principle behind finding a fraction of a number, such as 3/2 of 63, is rooted in the method of cross-multiplication.

Consider the following proportion: 3 2 = x 63 (where x represents 3/2 of 63)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 3 × 63 = 2 x
  2. Which gives: 189 = 2 x
  3. Divide both sides by 2 to isolate x: 189 2 = 2 x 2
  4. Which gives the result: 189 2 = x

Thus, 3/2 of 63 is equal to 189/2 (or 94.5 in its decimal form).
