Alaska vs Montana

Alaska is the largest state in the United States and has a surface area of approximately 588,000 square miles. Montana has a surface area that is approximately 25% of the surface area of Alaska. What is the approximate surface area of Montana?

Correct result:

M =  147000 sqm

Solution:

$$\begin{gathered} A=588000\text{ sqm } \\ M={\displaystyle \frac{25}{100}}\cdot A={\displaystyle \frac{25}{100}}\cdot 588000=147000\text{ sqm} \end{gathered}$$
