What is 10/10 of 45?

Often, in mathematics or everyday life, we need to find a fraction of a given number. For instance, how would you quickly calculate 10/10 of 45? We'll show you a straightforward method to achieve that.

How to calculate 10/10 of 45?

  1. Multiply the whole number by the numerator of the fraction: 45 × 10 = 450
  2. Divide this result by denominator of the fraction: 450/10 = 45
  3. Simplify by dividing both the numerator and denominator by their GCD (10):
    • 450/10 = 45
    • 10/10 = 1
  4. Which gives: 45/1

How does it work?

The principle behind finding a fraction of a number, such as 10/10 of 45, is rooted in the method of cross-multiplication.

Consider the following proportion: 10 10 = x 45 (where x represents 10/10 of 45)

  1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: 10 × 45 = 10 x
  2. Which gives: 450 = 10 x
  3. Divide both sides by 10 to isolate x: 450 10 = 10 x 10
  4. Which gives the result: 450 10 = x (or 45 1 = x )

Thus, 10/10 of 45 is equal to 45/1 (or 45 in its decimal form).
