Solving Mathematical Puzzles: If 18220000 is 45% of x, What is x?

Have you ever wondered how to solve the puzzle, 'If 18220000 is 45% of x, what is x?' This is a common type of problem often encountered in various fields, from finance to science. Let's break it down step by step to help you solve it accurately.

Understanding the Problem

The problem can be stated as a simple equation. Here, 'is' means the equals sign (), and 'of' means multiplication (x). Therefore, the problem translates to the equation:

18220000 0.45x

To solve for x, we need to isolate x on one side of the equation. We can do this by dividing both sides by 0.45.

Solving the Equation

The equation is:

0.45x 18220000

By dividing both sides by 0.45, we get:

x 18220000 / 0.45

Enter this into a calculator to obtain the result:

x ≈ 40488888.888

Alternative Methods

Another approach is to eliminate the decimal by multiplying the numerator and the denominator by 100/100, which does not change the value of the fraction but makes it easier to handle:

x (100/100) × (18020000 / 0.45)

This simplifies to:

x 1802000000 / 45

We can further simplify this by reducing the fraction:

x (5 × 360400000) / (5 × 9) 360400000 / 9

This results in:

x 40044444 4/9

Conclusion

Understanding and solving percentage problems is crucial in many real-world applications. Whether you use the straightforward division method or the alternative approach to eliminate the decimal, both methods effectively lead to the same solution.
