What is 1/10 of 48?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 1/10 of 48? We'll show you a straightforward method to achieve that.

How to calculate 1/10 of 48?

  1. Multiply the whole number by the numerator of the fraction: 48 × 1 = 48
  2. Divide this result by denominator of the fraction: 48/10 = 4.8
  3. Simplify by dividing both the numerator and denominator by their GCD (2):
    • 48/2 = 24
    • 10/2 = 5
  4. Which gives: 24/5

Since 24/5 is an improper fraction, the result could also be expressed as a mixed number: 4 4/5

How does it work?

The principle behind finding a fraction of a number, such as 1/10 of 48, is rooted in the method of cross-multiplication.

Consider the following proportion: 1 10 = x 48 (where x represents 1/10 of 48)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 1 × 48 = 10 x
  2. Which gives: 48 = 10 x
  3. Divide both sides by 10 to isolate x: 48 10 = 10 x 10
  4. Which gives the result: 48 10 = x (or 24 5 = x )

Thus, 1/10 of 48 is equal to 24/5 (or 4.8 in its decimal form).
