Memorizing the formula for calculating percents is the easiest way to solve the problem "What is 45% of 50?”. That's why this method is taught in mathematics lessons of schools, because you do not need to know anything about fractional numbers or proportions. Learning the formula will be enough for calculating. The main thing is to correctly determine its components.

The general formula for calculating percentages looks like that:

  • (Percent × Whole):100 = X

There are 50 is the Whole, and 45 is the Percent, but the X is the desired result.

So, you can to get an answer to the question «What is forty five percent of fifty»:

And next just multiply the resulting decimal number with a Whole (with 50):

  • Whole × Percent = Part (X)
  • ✔️ 50 × 0.45 = 22.5

You get 22.5 again! So, we can use equivalent forms of percentages interchangeably and choose the one(s) that best suit our purpose.

What is 45% out of 50 using a proportion?

It is a good method which can show you what is 45 percent of 50. Recall that 50 is a Whole, and a Whole is 100 Parts.

Let's make an equation from this proportion to calculate the Part. We need to multiply the numbers cross by cross:

  • X * 100 is equal to 50 * 45 or X*100=50*45

Let's solve this equation and find the unknown:

  • X=50*45/100
  • X=2250/100
  • ✔️ X = 22.5

Interestingly, the diagram of 45% from any integer will look the same. Because it is always 45 parts of 100 something. Although the answer to the problem will be different, the picture will be the same. For example, 45% of 100 would be 45, which is 45 parts of 100 parts. And the blue part will always take up 45 percent of the circle, because it's always 45 parts of 100.
